Is there a way to reproduce this? and does this happen with only patcher?

I'm unable to find any reason why this might happen.

[hannibal002]

Sadly no.

I used the same version of patcher for months and restarting with patched 5-20 times a day (testing mods) and it only happened 2-3 times in the last year over multiple versions of patcher. After the crash today, I tried starting again without touching mods at all and it worked fine the second time. Therefore, I think the crash it is not linked to other mods, at least not directly.

It feels like a 1/1000 chance edge case thingy. Maybe just throw a catch block around this case?

[Sychic]

Can't just blindly catch an exception which might stem from a deeper cause...

If it's not consistent then it's likely not patcher's issue and you may want to update if you haven't already.

[hannibal002]

You think ignoring this crash could corrupt other mods/config files down the line?

Maybe a race condition like behaviour with mixin?

[Sychic]

There's no mixin involved here, it's something completely different (at least afaict). I doubt it's that big of an issue because there's no data involved here (if you're reading or writing files in render, you should really reconsider your setup).
