From someone in the Discord you can try this:
Open terminal and run
__GL_CONSTANT_FRAME_RATE_HINT=3 steam -resetLet it reinstall and update Steam, once finished sign in/2FA into Steam. Then exit, launch Steam by clicking the desktop shortcut this time, it’ll ask you to re-log in/2FA. after you’ve logged in a second time, it should work from the shortcut again without asking you to sign in an additional time.
