Symptoms

The game starts and immediately crashes.

I found that you can get the game to actually keep running if you edit the file at steamapps/common/PICO_PARK/save/userdata.lua and change isFullscreen=1 to isFullscreen=0 (and while you're at it, change soundVolume=10 to soundVolume=3 cause it will be loud at 10). Then set the launch options to PROTON_USE_WINED3D11=1 %command% or PROTON_USE_WINED3D11=1 %command%.

The game will run BUT the screen will only be black. I can still hear the game, and even the character jumping when I press the spacebar, but there are no visuals.

Reproduction

Install and run.

Start by reviewing the linked Proton log and reproducing the crash with Proton Experimental, Proton 6.3-5, and Proton 6.12-GE-1. Compare the default launch with the userdata.lua changes and PROTON_USE_WINED3D11=1, then determine whether the failure is specific to fullscreen or rendering. Done means PICO PARK starts and displays visuals without requiring a black screen workaround.
