Had the same issue, solved it by downgrading kwin from 5.22.5 to 5.22.4 following these steps:

  1. Download downgrade from the AUR: yay -Sa downgrade
  2. Show kwin version list: sudo downgrade kwin
  3. Now you’ll have a list with kwin versions and a number corresponding to each version, you must type the number of version 5.22.4 and hit enter
  4. When asked if you want to install say Y
  5. Reboot your system: Reboot

PS: You might be tempted to use downgrade to install new version 5.22.90, don’t do it as it won’t work (you won’t be able to go past login screen).

Now we wait until 5.22.5 bug is solved.
