Crashes using multicam

I am facing some strange crash issues when working with multicam. Especially when i add a clip manually that was not synced by davinci. Once the clip is on and i want to work with it it crashes. When i reopen davinci it instantly crashes when i just click on the multicam clip. The originally synced clips are for some reason red in thetimeline.

What camera was used to film that problem clip?

4K on GH5 (but with 8bit)

OK. I wouldn't expect that clip to cause any issues.

Go to the Media page, in the Media Storage panel top left, and navigate to the folder that has that problem clip. Can you play it there?

Yes it works. But i think i found the issue. I had 4 clips in the multicam sync. Davinci could not sync one specific clip so i've put it manually into the sync folder and synced it by hand. For any reason this caused the issue.
