After every single game, when the LoL Client opens back, it shows the popup “Your session has expired. Please login again to continue”.
The same error appears when I’m idle for around 10 mins in the client.
There is nothing about this on the website.

Distro : EndeavourOS fresh
Wine build : wine-ge-lol-8-27-x86-64
Game launched via Lutris with default config

I don’t know if it worked before, I installed Linux during the 13.23 issue.

Full Lutris log for an idle crash without any game started. No specific log appeared just before the popup.
