Kden refuses to open up again.

I accidentally clicked on the triple Monitor layout I had and I only run one Monitor and then it crashed.

And then it did not want to open anymore. Everytime it crashes immediately with startup. I deleted every config file and the same error persists. I re-installed, purged, all the good stuff it always just says "It crashed last startup, do you wanna restore the config files" and then it immediately crashes again.
I did try rolling it back, but that too, does absolutely nothing.

I am on LMDE 6, Flatpak.

Honestly no Idea what else I can do at this Point. <_< Any Ideas what I might have missed?
