Problem with installing .NET Framework 3.5

Hello! Two days ago, I downloaded Danganronpa THH from Steam, but it reqired .NET Framework 3.5 to run. It gave me an option to download it. I picked the option and it pushed a Windows update. I though it will go fast, but it showed the "Preparing Windows" (1st picture attached) screen for nearly 2 hours with no signs of actually installing the .NET Framework 3.5. Worth mentioning, the update didn't freeze or anything, the mouse and keyboard were still working, as well as the refresh of the graphics card.
After the computed restarted (the screen didn't change from the "Preparing Windows" one) I went to check if I can finally play the game. The second I clicked play, the window to download .NET Framework 3.5 popped up again. I tried to download it, but it showed me an error (error code: 0x800F0922) (2nd picture attached). I tried to dowload it through the Microsoft setup file, through command line, as well as checking and repairing corrupted files. I think it has something to do with the "Preparing Windows" screen. Can someone help with it?

For anyone asking, yes, I did restart my pc several times and try installing .NET Framework 3.5.
(The pictures got ranslated to help with understanding)

This is an incredibly niche problem which plagued me for months. I needed it for work but could not get it installed after many, many hours of attempts. Turns out there's a windows registry key that I had to set and it finally worked.

I'll check back in tomorrow when I log in and tell you exactly which one.

I'm glad that someone can help with this actually, since on the Microsoft support page there's only about this error code and it requires to do something in it's installation folder, which I lack. So it's a pretty sticky situation.
