CS2 Stuck on Valve Logo on startup 545 beta branch

Waited about 3 minutes or so. Under x11 dota and cs pretty much start instantly. I can try again and let it run for a while and report back but with 535 under wayland, this only ever takes a couple of seconds from the logo to mainmenu.

EDIT:
Also just from looking at CPU/GPU utilization, there is no shader compilation happining while the game hangs at the splash logo.
