My nixos config has been working fine for the last couple of days, but today i got this error and im unable to change my brightness im unsure why. Here’s the log from startup:

Yes I think an update of my packages caused it to break, i have done numerous rebuilds of my config and updates of my flake.
How you call changing brightness?
I have tried both the brightness up/down button and the qdbus command, which gives me the same errors as the logs shown:
