System Settings “Extension process exited” error after installing macOS 15.4 on MacBook Pro 15” 2017

Hi! I installed Sequoia 15.4 on my MacBook Pro 2017 15” (MacBookPro14,3). Installed it on top of Ventura with all my files kept and clean install without signing in to iCloud, but the problem persists.

The installation went fine, and everything works except, when when trying to enable accessibility access for apps, or allowing background apps, the error: Extension process “x” exited. Pops up. And can’t make changes.

Anyone else has this problem? Does anyone have a solution for this?
