Batch Generate-Previews doesn't work anymore
Closed, ResolvedPublicBUG


System Information
Operating system: Windows 10
Graphics card: MSI GTX 1080

Blender Version
Broken: 2.83.2
Worked: 2.80

Short description of error
The "Batch Generate-Previews" does not work anymore. The little processing black square just pop out and disappears after a second. I tried on an old version of Blender (2.80) and it works just fine. The processing square stays way longer on the old version. With the new one, it seems that the process doesn't succeed.

Exact steps for others to reproduce the error
Save a file with a basic cube.
Click on the "Batch Generate-Previews" tool
Try to append with another file -> no preview has been exported
