Crashes BTD6 when going into a game (or sandbox)

[BearyI23]

I am using MelonLoader 0.6.0 ALPHA Pre-Release (Windows amd64) with Modloader 3.1.1 on the Windows version 34.3.6116 of BTD6. I am running Melonloader and BTD6 through Proton in Steam on PopOS (Linux).

When Boss Rounds 1.0.3 is enabled the game load fine but crashes when trying to go into a game (and sandbox).
Here is a screenshot of the MelonLoader log right before the game closed down:

Are you able to reproduce the issue when using just Mod Helper + Boss Rounds and no other mods?

[BearyI23]

yes it still crashes with only mod helper and boss rounds.
(also sorry for the late response.)

Can confirm issue still exists on 1.0.5 on Linux.

EDIT: Can confirm also still happens on 1.0.6
