Ubuntu 22.04 Anaconda - clicking Jupyter tile launches other programs instead of Jupyter: pgadmin4, calibre - anaconda

I have a new install of Ubuntu 22.04. I installed Anaconda. However, clicking the Jupyter tile launches other programs such as pgadmin.
Setting pgadmin to a fixed port fixes nothing. Removing pgadmin completely, and clicking the Jupyter tile then launches calibre.
Can someone tell me how to fix this?

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.

R is dead in Jupyter

I have instaled R in my jupyter through anaconda and It was working fine. Today I found this message when I opened R form Jupyter and I don't know what is the problem ?
The kernel has died, and the automatic restart has failed. It is possible the kernel cannot be restarted. If you are not able to restart the kernel, you will still be able to save the notebook, but running code will no longer work until the notebook is reopened.
I'm using Mac OSX
I had the same problem in Mac OSX when R is installed before Anaconda. The fix is to:
1. Uninstall R and Anaconda
2. Install Anaconda
3. Install R

Issue in launching spyder that was installed using pip install on Python 3.6.1

I have windows-7 64 bit machine and Python3.6.1(32-bit) installed on it. I wanted to try spyder as IDE for python. I don't have Anaconda or anything like that. So, I installed spyder from command line (cmd.exe) and it did install successfully and prompt returned.
I think it is installed because
I can see spyder3.exe under C:\Users\UserName\AppData\Local\Programs\Python\Python36-32\Scripts
From cmd.exe when I enter spyder3 it doesn't throw any error and a rotating circle appears which indicates something is processing. But nothing is launched.
After running spyder3 from cmd.exe though nothing gets launched except the rotating circle for couple of seconds, I see spyder.lock folder under C:\Users\UserName\.spyder-py3
When I delete spyder.lock folder under C:\Users\UserName\.spyder-py3 and run spyder3 again in cmd.exe the folder is created again.
Question: How can I make spyder launch? Did I do something wrong while installing spyder or am I trying to launch it with an incorrect method?
I had to install PyQt5. It is a requirement for spyder on windows and I was missing it. After I installed it I can launch spyder3 from cmd.exe
