Lightroom 9.1 crashing on import since Catalina 10.15.2 Update

Hi!

Since updating to Catalina all my imports crash. I tried to import from card directly and by copying to disk first. I use copy as DNG and it creates the folder and also all dng files correctly. But as soon I select that folder in LR the programm stucks. Nothing helps to bring it back to live. Closing LR is also only possible by using alt-command-esc. After closing it that way its impossible to start it again without restarting the macbook. After the restart, LR works without any problems and can also open the folder created by the stuck import without any issues. I´m using Lightroom 9.1 with macOS 10.15.2. My catalog and images are on a Samsung T5. Any ideas on that?
