NOTE: I cannot see this script working on amd cards or off fedora.

Hello @C10udN9n3, this is neither a compatibility report giving information to help a Proton dev identify something to improve in the project or something tthat can be integrated into the project.

Closing as invalid.

So what logs do you want? I tested, retested, and compiled what worked for me into a script. The known issue for me is proton defaulting to windows XP or 7 compatibility, then dotnet not liking the sandbox. The error windows were not informative at all at the actual issue, providing no links or file paths to logs. In addition the vessels were limiting memory capacity, then causing dotnet installs to hang and crash.

Nothing extracted yet.
