Thank you @sergecleantalk , the ticket has been created.

I also can confirm the issue with empty thumbnails after update from 1.10.3 to 2.0.24 (system information is included below).

Purging all possible caches didn’t help, lazy loading is disabled, so I’ve recovered the previous version from backup as an immediate solution.

Look forward for the positive news, thank you very much for your efforts!

The very best regards,
