Research direction
Start by reviewing steam-2640d.log and steam-2640.log, comparing the launch behavior with and without PROTON_OLD_GL_STRING=1. Reproduce the launch failure and the GUI text bugs using Proton 5.0-6 on the reported Linux/NVIDIA setup. Done means the game launches without that option and its GUI text renders correctly.
