Try a new PSU, the only way to troubleshoot some PC issues sometimes is to just swap a part one by one starting with the most likely culprit. In this case, the PSU.

Run Furmark and AIDA64 at the same time

You could try reducing your power load by temporarily disconnecting any drives you don’t need to run the game, and if your ram is 4 sticks then going to 2.

If the game then works you’d know it was a power issue.

100%ing your components might not trigger the issue, it might be triggered by a combination of components being used in a specific way. Might be worth giving some purpose-designed stress tests a go, such as furmark, cinebench & prime95. There's a chance something unusual the game is doing is also causing a power spike that's tripping something, this would usually be something updated drivers would mitigate (Nvidia had this issue with some 3xxx cards at launch) and this would still have the root cause of your system being able to draw more power than your PSU allows.

Regardless, no software should be able to cause the behaviour you have described without a corresponding hardware issue though.

To me, it definitely sounds like you're triggering the PSU overpower protection (though kinda weird the game only triggers it after the first launch). ~~This might not be universal, but you can sometimes reset the protection sooner (the delay between allowing you to boot again) by cutting the power at the wall for a few seconds. Maybe trigger the issue and then try that, if you can boot again quicker than it was letting you, this is your issue.~~ just read that you tried this, perhaps your PSU doesn't allow you to reset the breaker like that (I've never used a be quiet one)

You could also possibly just be unlucky and have an early PSU failure, but given it's pretty new, a repair would probably be covered by warranty. If you have the option to try with an appropriate spare, that might be worth a go.

I waited for 4 months before the fix dropped.

Try disabling all overclocking / boost features. I believe Amd has like 2-3 overclocking methods.

Hmmmm.... Another thing I've run into, but my result wasn't as severe (usually just a hard crash of the game, but sometimes a full crash). I've had a GPU that had 1MB less of memory than was advertised. While minor, the GPU would advertise this space to the system, and when that ghost memory was allocated, it would lose its mind. Skyrim's support team was the one who discovered that headache.

Most games would run just fine because they didn't try to max out my GPU. Just the ones that tried to get the most out of every byte.

Unfortunately, the only test and fix was a new GPU for that one. I went a long time simply not playing some games.

Crashing it yes, preventing it from turning on no, I would say OP should def check his psu still, but it sounds like the game is exacerbating existing issues

This is nothing, there was a game (demo?) in the 90's that wiped your entire C drive when uninstalling.

A lot of comments in this thread complaining about performance issues:

Thread that OP updates several times saying he's found no solution even after several hardware changes and software changes:

Another thread about it where people recommend changing the PSU:

Here's one where it's even happening on a PS5:

Here's a steam post where the developer gives a big nothing burger response:

Ah, whoops. If it's not in a Linux community I immediately jump to Windows :)

You probably have 2x32 GB RAM? Or 4x16? Sometimes the RAM configuration is wonky with more slots used, so really try to go with 1x32 (or 2x16) and see if you still have an issue.

But even in Windows Hell Let Loose had issues for me, like stuttering. Going from a 5800X to 5800X3D helped a little, but it could still run better.
