Firefox browser keeps crashing on troubleshooting mode
I was on firefox today and it suddenly crashed. I haven't installed any new extensions in over a week - I try reopening it and I see that the window opens and closes instantly. I've restarted my computer, uninstalled and reinstalled firefox, refreshed firefox, deleted folders that have cache in it in roaming & local, attempted to go into safe mode, tried to open the profiles. None of it fixes the problem, nor do the windows for firefox profiles and safe mode stay on enough for me to even look at it. I assume that it keeps crashing, but I can't figure out how to fix it. The browser is stuck on troubleshooting mode now.
Here's a link of how it looks like to me now (not sure if links are allowed though).
Let me know if I should give any information to help solve it.

You can check for issues caused by a corrupted or incomplete Visual C++ installation that is missing runtime components (Redistributable Packages) required by Firefox, especially VCRUNTIME140_1.dll.
In that case, I would install both 32-bit and 64-bit "Visual Studio 2015, 2017 and 2019" downloads, (x86: vc_redist.x86.exe and x64: vc_redist.x64.exe) from https://support.microsoft.com/help/2977003/the-latest-supported-visual-c-downloads

Okay, how can I check for issues? I've never run VS before.
Install both the programs listed.
