Both 20/24 don't work on my PC, no apparent reason

Yes, I’ve done a lot of searching online, and even asked several Facebook groups about the issue, yet still no help.

So briefly, I got myself a new TV, hooked it up and 2020 started to fail. It would crash on the loading screen, if not, it would freeze completely on the home page, or after a few minutes at the gate.

Decided to do a reinstall, which took 3-4 hours. Tried to launch it and this time around it would crash on the loading screen after a couple of minutes.

After another reinstall, which weirdly enough only took 5 minutes, I would try to launch it from the Xbox App, and a message appears saying the game has crashed, with the exception code (0xc0000005).

Tried to launch 2024, and that doesn’t even start up at all. Only the initial title/picture appears and then it’s gone after like 10 seconds.

Tried to launch 2020 with no Community Folder, and that didn’t help.

Bit of a dilemma. Read about a possible BIOS update, but that asks for a Bitlocker Recovery Key which I don’t even have.

Really hope I can get some help, seems ridiculous to me, that everything just stops working.

Thanks in advance.

That exception code is very hard to track down the cause.
There is a post here on how to go about trying to find it:
