[Solved] Polkit doesn´t Start on KDE Wayland

Setup:

OS: Arch Linux x86_64
Kernel: 6.12.40-1-lts
Packages: 1125 (pacman), 9 (flatpak)
Shell: zsh 5.9
Plasma 6.4.3
WM: kwin
Terminal: konsole

Hi,

i don´t get a PW Prompt anymore by starting progs who needs root (For example Timeshift or UFW). I can still open them per Terminal but not per GUI Prompt. Problem is Polkit doesn´t start if i understand it rigth so far. When i try to start it manually with my user i get:

/usr/lib/polkit-kde-authentication-agent-1 &
[1] 89120

New PolkitAgentListener  0x5ffe6b8e9c90
Adding new listener  PolkitQt1::Agent::Listener(0x5ffe6b8e9960) for  0x5ffe6b8e9c90
Listener online
"Cannot create unix session: No session for pid 89120"

** (process:89120): CRITICAL **: 16:01:58.661: polkit_agent_listener_register_with_options: assertion 'POLKIT_IS_SUBJECT (subject)' failed
"Cannot register authentication agent!"
Authentication agent result: false
Couldn't register listener!

[1]  + exit 1     /usr/lib/polkit-kde-authentication-agent-1

It worked before, and i cant say when it crashed, maybe a few days ago, maybe a few weeks. Anybody know what to do and can help?

Best
Pampa

Edit: Had a hardening Problem in /etc/fstabproc /proc proc rw,nosuid,nodev,noexec,relatime 0 0 was with hidepid=2 included after excluding it it works again
