Should I attempt to reinstall?

It happens on all the systems I installed openmamba on though 🤔

I have reinstalled openmamba using the openmamba-livecd-en-snapshot-20251107.x86_64.iso image and as soon as I opened firefox (for the first time after logging in) I was given the kde wallet password request.
It happens on both Wayland and x11, I use x11 on this one system in particular because of the nvidia_470 package that is not supported by wayland (the nvidia package has its own problems recently according to the reports I've submitted).

While the nvidia-470 installation may have a history of its own, I suppose the Ryzen PC is running with standard drivers and you are reporting the kwallet problem as present on both. By the way it seems you only sent reports of the nvidia-470 PC. A report from the Ryzen PC might be useful to try to make a diagnosis of the problem.

The new received report is about a Intel Core 3 CPU based hardware. The log shows a series of crashed which would suggest investigation:

A useful backtrace for these coredumps would be necessary. Unfortunately
- the packages installation log shows that the last package was updated on October 20, in order to try to install the needed debug packages they should be aligned with current repositories, so the system should be updated first
- drkonqi itself is crashing so no crash helper would be available on the desktop

I suggest to update the system, try to install some debug package like:
sudo dnf install gnupg2-debug kwalletmanager-debug qt6-qtbase-debug

reboot, reproduce the problem and generate a new report. By having the system up-do-date the more recent coredumps can be shared in order to try to obtain a useful stack trace.
The more useful would be the one related to gpg-agent as is it probably the cause of the subsequent kwalletmanager5 crash, but first it has to be confirmed that after the system upgrade it gets these same processes to crash.
