After the update I'm getting a black screen just with the cursor.

Killing the app and starting it again seems to prompt a recover interface and check assets. But after that is done, the black screen starts again.

Most of the errors are related to:

[1076] No mesh data available for mesh sftorusknot on particle system Up_Whirls. Make sure Read/Write Enabled is set in the importer to work on the particle system renderer
