Lightroom classic 10.1 on Mac OS Catalina stops recognizing HEIC files

[kollers]

Hello,

Since the recent update (either 10.0 or 10.1), lightroom stops recognizing HEIC files randomly (black circle with the "!"). This immediately affects the Sync: all HEIC files are put into a smart collection "Sync errors".

Restarting the app helps, but I think it's a bug. Did anyone experience the same? Is it planned for correction?

My tech:

• MacBook Pro 13, Mid-2012
• MasOS Catalina
• Lightroom Classic 10.1

Thanks for your help.

Best regards,

Vitaliy

Where did you import the  photos to?

What drive?

Hello,

The photos are on the external HDD, and I imported them back in May/June.

Now they are in a LR Sync collection and they get this bug...
