Update:

After further investigating I found the same error occurs when running PeerTool in the utility mod (RLM) directly. This mod is nothing more than a single new class and some new prefabs. No overrides or anything, so this should not be possible.

I copy-pasted the entire project source into a newly created project and everything works fine. So it seems quite apparent that there is nothing wrong with my mod source, WB is just straight up cooked and sometimes will randomly create a corrupted project that cannot be used with PeerTool.

See attached video, first example is a brand new project that I copied the entire mod source into, works fine. Second example is the original WITH THE EXACT SAME SOURCE but causes PeerTool to immediately crash with shader error.

After some assistance digging into this issue on Discord from reyhard, it turns out this problem is due to the long path the original mod had.

The path for my WB addons dir is:

/home/yeet/SteamLibrary/steamapps/compatdata/1874910/pfx/drive_c/users/steamuser/Documents/My Games/ArmaReforgerWorkbench/addons

With the mod folder being named Randomized Loadout Manager or RandomizedLoadoutManager it breaks, if I rename the folder to RLM it works fine.

/home/yeet/SteamLibrary/steamapps/compatdata/1874910/pfx/drive_c/users/steamuser/Documents/My Games/ArmaReforgerWorkbench/addons/Randomized Loadout Manager/addon.gproj 167 characters <- does not work
/home/yeet/SteamLibrary/steamapps/compatdata/1874910/pfx/drive_c/users/steamuser/Documents/My Games/ArmaReforgerWorkbench/addons/RLM/addon.gproj 144 characters <- does work

Given that WB is able to load this same addon path just fine it seems there is some issue specific to the PeerTool or diag client, perhaps they are using a different Windows FS API that doesn't support longer paths?
