Steam Deck in game mode, can't run

[bi0shacker001]

Trying to run F95Checker from Game Mode on the steam deck, even in nested desktop, results in error

Traceback (most recent call last):

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 115: ordinal not in range(128)

No log files are generated, this was captured by running F95Checker in the terminal. No extra debugging information comes from running the -Debug version.

The paths listed don't appear to reference paths on the host, so I'm unable to perform any additional troubleshooting, and I'm unsure how to bypass the bundled python libraries to test with my system-installed libraries
It runs fine in standard desktop mode.

theyre doing some weird stuff with text encoding, forcing it to be ascii instead of the default utf-8, for whatever reason
