SUMMARY Log in fails on Wayland since the latest kwin updates on my Neon installation, but works on X.

> This is failing to load plugins which indicates a setup issue rather than a kwin problem. Please ensure all your packages are up to date and installed. Thanks for the suggestion, I think this is definitely and issue because most likely incompatible versions of packages are installed by the package manager - or there is some other hindering issue somewhere, I am not expert of this domain. Regarding the suggestion, if you check the referenced KDE discussion, somebody else already suggested something similar, I followed every step, updated everything that I could and nothing solved this issue other than downgrading the referenced packages to their original version.
I happy to share other debug information if the already shared information is not enough to pinpoint the root cause of the problem.
I'll move this to Neon, maybe they can help.
The issue still occurs with the recent 6.2.5 as well. ``` Start-Date: 2025-01-04 20:38:12 Commandline: /usr/bin/apt install kwin-wayland=4:6.2.3-0zneon+24.04+noble+release+build14 kwin-common=4:6.2.3-0zneon+24.04+noble+release+build14 kwin-x11=4:6.2.3-0zneon+24.04+noble+release+build14 kwin-data=4:6.2.3-0zneon+24.04+noble+release+build14 Downgrade: kwin-wayland:amd64 (4:6.2.5-0zneon+24.04+noble+release+build21, 4:6.2.3-0zneon+24.04+noble+release+build14), kwin-x11:amd64 (4:6.2.5-0zneon+24.04+noble+release+build21, 4:6.2.3-0zneon+24.04+noble+release+build14), kwin-data:amd64 (4:6.2.5-0zneon+24.04+noble+release+build21, 4:6.2.3-0zneon+24.04+noble+release+build14), kwin-common:amd64 (4:6.2.5-0zneon+24.04+noble+release+build21, 4:6.2.3-0zneon+24.04+noble+release+build14) End-Date: 2025-01-04 20:38:15 ```

Could somebody help with at least additional debug steps that I can run to help with identifying the root cause of this problem that I experience on two different machines?
