qtile: Qtile semi-crash disallowing you to click or use key bindings, vol.2

In 2019 I reported #1445 and we considered it solved but it either continues to be broken or I have encountered a very similar issue. It behaves exactly like #1445, so I will copy-paste it here

Randomly, from time to time (~ once a week), it happens to me, that Qtile halfway crashes and

• I still see the desktop, it doesn’t disappear or fail or restart, anything
• I can move the mouse, but I cannot click on anything
• I can’t use my key bindings (I can use ctrl+alft+f2 to switch to TTY though)
• I can type to the focused window

This time, in ~/.local/share/qtile/qtile.log appears:

When I try to run qtile-cmd -o cmd -f restart or another Qtile command, I get:

Any help is appreciated, at the moment I am forced to deal with this by killall -9 qtile and it really hurts.
