Importing and relinking videofiles is going very slow (Sony a6700 files)

[Matthijs31399023w73x]

Since a few days my Premiere Pro is working very very slow. I'm trying to import soms MP4-files from my new Sony A6700 camera. Worked before, even the 4K 100f files. Now it's almoast undoable. It takes a lot time. After restarting the program, it also takes a lot of time to relink / load the video files. 

I already used the cleaner tool and i removed all other video editing software. Im using a Apple M1 MBPro, 16 gb RAM. Which always worked fine! 

Does anyone have a idea?

@Matthijs31399023w73x I have not seen this issue before. Would you be able to share a project and some A6700 files that we can use to duplicate this problem? 

Thanks!
