Failed to create IPA archive after upgrade to Xcode 11.4.1, VS for Mac 8.5.4, and Xamarin.iOS 13.16

After upgrading to the latest versions of Visual Studio for Mac, Xamarin, and Xcode, I am unable to create a signed IPA archive. Everything runs on the simulator, everything builds fine in my release configuration. I can even create the archive just fine. But after I click "Sign and Distribute", regardless of whether I try to publish to the App Store or simply save the IPA to disk, I get the extremely generic "Failed to create IPA archive" message with no other detail about what failed.
As always with these types of problems, this worked the last time I tried to publish (2 months ago). Even trying to use "Sign and Distribute" on an archive I previously published successfully to the App Store fails with the same message. Are there any logs for this where I can see exactly what is failing? The Archive output window at the bottom of the screen doesn't show activity for this stage of the process.
UPDATE:
After finding the logs, was able to see the following error that shows that for some reason after upgrading the apps, permissions were somehow lost for creating the zip archive:
zip -r -y "/Applications/Xcode.app/MyApp.ipa" Payload
zip I/O error: Permission denied
zip error: Could not create output file (/Applications/Xcode.app/MyApp.ipa)
zip exited with code 15
ERROR:Failed to create IPA archive.
Finshed
So now the question becomes why, and what steps need to be taken to fix this the proper way (i.e., not just brute-forcing broad permissions)?
Are there any logs for this where I can see exactly what is failing?
To find Mac logs through:
You can select the Go > Go to Folder menu item in Finder, and then copy and paste any of these paths into the dialog.
Visual Studio for Mac
~/Library/Logs/VisualStudio/7.0 (this number may change depending on
the version you are using)
This folder can also be opened via "Help -> Open Log Directory".
If you meet the Permission denied error in the log, this may be due to saving the IPA in the XCode.App folder. You can try a different location.
If you still meet problem, you can send a feed back inside visual studio for more help.
It's very likely due to permission issue while zipping the archive.
To check if it's your case:
Open the log folder at ~/Library/Logs/VisualStudio/7.0 or in Visual Studio for Mac Help > Open Log Directory
Find and open the last log file for publishing (like Publishing.yyyy-mm-dd__hh-mm-ss.log)
Scroll to the last rows of that file. If it contains something like this (see the block below) so it's your case
zip I/O error: Permission denied
zip error: Could not create output file (/Applications/Xcode.app/YourApp.ipa)
zip exited with code 15
ERROR:Failed to create IPA archive.
Finished
In this case, once you see Output IPA file popup, just choose other save location (Desktop for example)

"msadox28.tlb File is under windows system file protection" error while attempting to build an installer

I am trying to build an installer for my project. The problem is that i am unable to successfully build the installer with the following error:
ERROR: 'msadox28.tlb' should be excluded because its source file
'C:\Program Files (x86)\Common Files\System\ado\msadox28.tlb' is under
Windows System File Protection.
From what i can gather, this file has to do with ADOX and ADODB that i use to create, read and write data from a local access database. Excluding this file causes the program to not work at all when it has been installed, because it attempts to create a fresh database from scratch at first launch.
The program works fine and there is no errors with it, but i want to build an installer so that i can send the program to a few users to test it and the database component is the most important part of my project.
Can somebody please assist me with solving this problem?

Visual Studio 2013 error while trying to run

While I try to run it keep on alerting me "Error while trying to run project: Invalid pointer", please help
I think this problem is caused by importing VS2010 settings. Anyway, this solved the problem for me:
Go to \Users\<Username>\AppData\Roaming\Microsoft\VisualStudio\12.0
Rename the folder to '_12.0'
Repeat for \Users\<Username>\AppData\Local\Microsoft\VisualStudio\12.0
Open Registry Editor
Go to HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0
Rename the key to _12.0

Run a batch file during installation

I want to run a batch file – say driver.bat – after the application installation is completed. This has to be done using the Visual Studio setup and deployment while creating package. This question has been asked before, but the solution is giving me a problem: once the installation is done, it’s throwing an error message like:
'cmd.exe' should be excluded because its source file is under Windows File Protection
This issue comes when the file is marked as a protected file on the Windows operating system. You need to exclude the file from this protection to execute successfully. The following link would help you do so -

Jdeveloper 11gR1: java.lang.IllegalStateException when opening project

I installed 11.1.1.5 just now, and am getting this error every time I try to open a project or a directory in a project, I get the following error:
java.lang.IllegalStateException: Timer already cancelled.
And it doesn't display the files.
To exclude any other factors I did a fresh install in a new Ubuntu VM image - same problem.
I'm really at my wit's end.
I solved the problem by deleting all local projects and checking out the source code again.
