Same issue for me on Nobara 39.

Same issue here for Bazzite, which is based on Fedora Atomic 40.
Error message is pretty much a duplicate of OP.

Edit: I see that for bazzite there is a separate issue, although it could be the same cause as log does not show significant differences: #406

As a temporary workaround (if you are using X11), you can get it to work by:

WINIT_UNIX_BACKEND=x11 ./linux_BoilR
