Symptoms
After setting up the launcher settings, the game error message pops up with infinite Vertex Shader Compilation Error. Trying to bypass the error screen will result in a crash [after the game bootup sequence].




Proton Log (Proton Experimental) steam-229890.log
and of course: here's the FailedVertShader1.txt file alongside it.
(note: despite the title: it's actually a duplicated txt file after running the game six times in a row, hence FailedVertShader6)
Reproduction
Launch Joe Danger and set any graphics or input settings and play with the error message.
If using Game Mode (Steam Deck) and you don't have a KB/M around: you must assign any of the Inputs as Mouse Emulation and try to bypass it by pressing the Ignore button.
If using the Desktop Steam and you don't have a KB/M around (again, if you're using Steam Deck Inputs): you'd need to assign the Inputs as a Mouse emulation and try to bypass it by pressing the Ignore button.
If using on any Linux distro's and have KB/M connected to the PC: just press the Ignore button.

Research direction
Start by reading steam-229890.log alongside FailedVertShader6.txt, then reproduce the issue by launching Joe Danger with the listed Proton versions and bypassing the shader error. Confirm the behavior across Steam Deck Game Mode and desktop input setups; the issue is done when the vertex shader error and resulting crash no longer occur.
