Firefox will not start, cursor blinks
Firefox recently stopped working. I tried uninstall/reinstall, removal (name change) of AppData\local\Mozilla, local low and remote folders before installing. All the same result that when I click Firefox, the cursor will start to flicker, the program shows in the task manager but never starts. When the AppData folders were removed, new ones were not created.
The only to changes were that I was given temporary admin privilages on Avecto Privilage Guard and I installed Visual Studio 2022 - removed 2019 as well.

Maintenance: (Programs Folder) <Windows Only> Firefox itself: (Programs Folder) And two folders in the profile of each user on the computer for each Firefox profile for that user.

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.
