This is half a year too late, but perhaps it'll help someone else. I notice that OP is using Revo Uninstall too. That was the cause of my "Your Vortex installation has been corrupted" error. Entirely my fault, because I used Revo too aggressively.
This is how I solved the corruption without reinstalling.
I got this error on Vortex Launch:
[Window Title]
Installation corrupted
[Content]
Your Vortex installation has been corrupted. This could be the result of a virus or manual manipulation. Vortex might still appear to work (partially) but we suggest you reinstall it.
[Quit] [Ignore]
Press Quit. That will exit Vortex and keep your error log small. If you press Ignore, then it will be too large to be useful.
Open vortex.log in Notepad++ and scroll to the bottom of the file. If you check the timestamps, you only need to worry about the ones from your last launch attempt.
Here's what mine looked like:

Do you see all of those missing "rimworld" files? I knew instantly what had happened. A few months ago I removed Rimworld using its uninstall process. It looked like Rimworld (and its expansions) weren't fully and cleanly uninstalled, so I removed them with Revo Uninstaller a few days ago and I told it to be thorough (scrub the registry and any odd Rimworld files).
I've grown to trust Revo Uninstaller, so I didn't double check its work. I approved the files it wanted to delete. Evidently, it'd decided that Vortex's built-in Rimworld files were part of Rimworld's installation and needed to go. And that's why my Vortex installation was corrupted today.
I went to my Recycle Bin and recovered the game-rimworld folder.
Vortex now launches with no errors. Problem solved!
It took longer to make this post than to troubleshoot and fix the problem.
Good luck to y'all. And much love to the programmers for sending useful messages to the vortex.log file.
