Some applications including Anaconda Navigator and Command Prompt suddenly refuse to launch

After working in Anaconda's VS Code (and Microsoft C++ Build Tools), I restarted my computer. Afterwards, some applications, including Anaconda Navigator and Command Prompt, could not be opened anymore. I wanted to reinstall Anaconda Navigator, but even during uninstalling, I got the following error.
However, I proceeded and then installed Anaconda Navigator. Unfortunately even now, it would not open.
Any advice would be appreciated.
After many failed attempts at resolving the problem peacefully, I simply resetted Windows (Settings>System>Recovery>Reset this PC>Keep files), and now it works again.

Spyder Debugger Crashes

Mac OS 12.2.1
Anaconda Navigator 2.1.2
Spyder 5.1.5
I’ve been to the Spyder Web site, performed what was described as “Basic First-Aid” as well as “Emergency CPR” without satisfactory resolution. The first symptom was that the debugger just hung. After performing the suggested fixes (updating Anaconda, Spyder, and Spyder dependencies, system re-boot, etc.), the debugger now reports: “OperationalError: attempt to write a readonly database.”
I’m at my wits’ end. I’m wondering if I need to completely re-install all of Anaconda. Is there a “best way” to do this? Is there a web site that I can consult that will demonstrate how to get a fresh installation?
ADDENDUM
So, I cleaned Anaconda from my machine (what a horrific experience!) and re-installed it, using conda for both tasks. I started Anaconda and then launched Spyder. Then I loaded one of my modules, set a brake-point in the editor, and boom! The Spyder debugger worked. However, the new installation of Anaconda was lacking a particular library: pyreadstat. I used conda to get this library. I then launched Anaconda again, saw that pyreadstat was now in the base(root) environment. I ran one of my packages (8 modules mainly consisting of numpy and itertools manipulations of N-D arrays) and everything worked, including calls to pyreadstat to read SAS datasets. Okay, everything seemed copacetic. So, I tried to debug one of my modules and the debugger failed again, returning the message: “OperationalError: attempt to write a readonly database.” WTF! Is conda trashing Spyder’s debugger in some mysterious way? I don’t get it. Why would pyreadstat affect Spyder. It must be conda.
To answer my own question, in the Mac Terminal app, I typed:
--> conda install -c conda-forge spyder=5.2.2
Boom! All is well.
I had the same problem on Windows10 with spyder version 5.1.5.
For me, updating Spyder to the newest version as suggested here worked as well. This can be done in two ways:
Console
Open the console or, if you're working on Windows, the Anaconda Prompt and type the following commands in order to first uninstall spyder, and then re-install the newest version (just updating didn't work for me).
conda remove -n myenv spyder
conda install -n myenv -c conda-forge spyder
The first command, remove, uninstalls spyder in the virtualenv called 'myenv'. If you don't use virtualenvs, just leave the -n myenv aside.
The second command, install installs spyder from the third-party channel conda-forge instead of the official channel defaults. This option is necessary in order to install a spyder version newer than 5.1.5
Anaconda Navigator
Uninstall Spyder: In the "Home" tab, select the correct virtual environment in the "Applications on" dropdown menu. Then click on the gear symbol in the upper right corner of the spyder tile and select "remove application".
Add conda-forge to your environment's channels: This is nicely described at the bottom of this page.
Install spyder again, in the way you did it the first time.
Click again on the gear on the spyder tile, choose "install specific version" in order to update to the newest version. Now, versions newer than 5.1.5 should be available.

Unistalling and re-installing anaconda while anaconda environment was open - can't open cmd anymore

I uninstalled and re-installed Anaconda on my Windows 64-bit while I had an Anaconda environment activated in my cmd. Now, cmd won't open anymore, unless I launch it as administrator (restarting computer and removing Anaconda as Path variable doesn't help). My guess is that my cmd is "blocked" now, as I didn't do "conda deactivate" before uninstalling Anaconda (can't say with certainty though that this was actually the reason, but it coincides with cmd not opening anymore).
Does anyone have an idea how to fix this?
The error message from the screenshot appeared while uninstalling Anaconda, and also when trying to re-install it.

anaconda3 4.4 (64bit) re-install error

I installed Anaconda3 4.4 on my win10 laptop and everything went well. When I started spider the Kernel wouldn't start. and my anti virus (AVG) popped up to block something related to the program. I shut spider and anaconda navigator down and tried to reopened them, however the icon to start anaconda was removed i looked in the folder as well and could not find an exe file for it either. so i tried to uninstall. i ran the anaconda uninstall feature provided by Continuum and then tried to reinstall the program. and i get an error message "Failed to create Anaconda Menus" I'm not sure what to do from here
I did go in to AVG and delete the quarantined file from it. and i went through the registry as stated here How to remove anaconda from windows completely?
On the Start menu, enter "Control Panel" in the search box and select Control Panel from the results. Under "Programs" you should see "Uninstall a Program". You should find Anaconda.
