4.2.0: "ModTek Died!" on Steam Deck

[MaridaConnoisseur]

I have added './run.sh %command%' to Launch Options and changed compatibility settings to Steam Linux Runtime 3.0 in order for ModTek to even load, as it refuses to load from the default Proton selection. From running run.sh from terminal, I get a lot of errors of being able to load mono libraries, and failing to hook seemingly everything before 'terminate called without an active exception'. Simply double-clicking run.sh, the screen flashes black. Running from Steam gives the "ModTek Died!" error
Attached: log files.

The normal way is to run it from steam.
I am concerned about the following error (Illegal..):

01:02:16.0670407 ModTek [ERROR] Uncaught ModTek exception!
	System.ExecutionEngineException: String conversion error: Illegal byte sequence encounted in the input.

as that might indicate some special characters where they should not be.

Maybe its an issue with %20 in
XAI%20Logo
and
Custom%20Components
and
XAI%20ReSize

in ModTek.log they appear as whitespace
in assemblies_loaded.log they appear as %20

can you rename the folders to remove the whitespace and try again?
If that works, I have to check where the conversion form whitespace to %20 happens in ModTek code.

I've also updated ModTek@latest to avoid using get_FullName in the first place.
See https://github.com/BattletechModders/ModTek/releases/tag/latest

This is just an ugly workaround, as the "Ilegal byte sequence" error hints at a fundamental issue somewhere.

run.sh was updated to work with the newest Steam on Linux (and probably Steam Deck)

also ModTek 4.2 now provides an older HarmonyX version that you can try to see if it is stable
