Hello Community!
[ FIY: I use Lightroom Classic in German language, therefore the screenshots are in german. I translated everything below the pcis.]
Lightroom Classic should support HEIC files since 2019. Unfortunatly it´s not working for me right now. When I try to import the files I get the following error during selection of the pics:

EN: Preview for this file is not available
When I try to import these files anyway I get a grey window with - for sure - no preview.

When I try to edit the photo I get the following error:

EN: An unknown error occured.
Do you have an idea what could be wrong? I really have no clue yet. 😞
Wishing you a nice day!
