Error Compiling Accelerated renderer Error movie unable to produce frame

Hi,

When I want to render videos in the timeline, I get the following error

I already started a new project with the BMPCC 6k .braw files (6k solution) and I restarted my computer. Some of the Clips are rendering in the timeline (the color moves from yellow to green).

The error message says:

Around timecode 1:49:01:01 - 1:49:02:05

or when I try to render other files it says:

But my timeline is not even reaching until 1:49..., as you can see here:

I did only a very few normal cuts in this project until now, maybe some color corrections as well, but no complex effects.

I still have the files saved on my original drive (SSD). At the moment they are on very new external 5 TB hard drive, it's the first time I'm using this hard drive.

Thank you!
