can't work in project or export gives an error every time I try to do something in the project

A very important project of mine (musicvideo for client) has been bugging. It worked firstly perfectly fine, but quite unexpected priemiere has recently been giving an error everytime I try to do something in the project, such as playing it or exporting. Ive tried multiple things... Importing the workspace of the project in another project, resetting the default settings, copying the project, a previous and newer premiere version. All didn't work, please help.

Version of now downloaded premiere: 'Adobe Premiere Pro' 24.1.0 (build 85)

computer specs:

Macbook Pro 14-inch nov 2023, Apple M3 Pro, 18GB, Macintosh HD (

512,37 GB from 994,66 GB used) , Sonoma 14.5

Maybe also good to mesnsion the project is on a external samsung ssd, but premiere already has acces so woulnd't think thats the problem. Also the project is concverted from older to new version, and worked fine for a day but then the crash came up. Also already restarted computer ect.

Any help would be really appreciated,

kind regards
