Crash if a local mod file is a symlink

That's likely a change due to the unity upgrade - either that or if you run steam containerized it could be a change in them preventing steam from reaching out to your files proper, there's been a lot of this going on lately.

If you wouldn't mind doing an strace of the failure that would be very helpful in seeing why it fails now and if there's anything we can do to fix it. Otherwise to mitigate you might look at bind mounts instead of symlinks.

Any suggestion on the right params to use?

strace -o /path/to/logfile.txt %command% doesn't help

How long do you have before it crashes? Running from steam and attaching an strace is great if you can do it. Another option is to rename the original binary and replace it with a shell script that runs the renamed binary under strace.

Note you can probably get away with -efile since we only care about filesystem stuff. Cuts the noise a bit.

Since I can also start without translation and make the game crash when clicking on the translations button, that helped. So, `strace -efile -fp <PID>` gives hints. The game considers the file doesn't exist:

And I presume that when you're operating in shell it does exist? If so, I would suspect that you're dealing with a side effect of the containerization of steam trying to keep you safe from malicious games going and reading random files on your hard drive and the change is unrelated to the oxygen not included update.

Looks like that, a symlink pointing to the same folder doesn't cause a crash.

Alright, that's not convenient but I have ideas to work around this.

As I said earlier, you can look at things like bind mounts to put your translation resources inside the container's namespace
