When I open a project , godot has a 50 percent chance of crashing(crash 4 times of 10)
I don’t know how to fix it.
Here is the log:

[xcb] Aborting, sorry about that.

Yep, known issue with libx11:

On Archlinux the Issue has been fixed.

So you have to make sure to upgrade to a fixed Version or an older Version of libx11.
