Resolve starts by building thumbnails for everything in that folder. If there are a lot of clips, or the media is highly compressed like H.264, that can take a while.

Might that be relevant here?

Thanks for your response.
If I open that 'other folder' first after restarting Resolve, then Resolve does not crash.
