Do you have a save and are you able to reproduce this?

Unfortunately I do not have a save, as it happened after few minutes and before autosave.
I will try again and see if I get the same error.

edit: here is a autosavefile 1 minute before I got the error message again: https://1drv.ms/u/s!AunYMGlj31WakKxo0ox3bb5DIGYxdQ?e=EuwDXA

Wasn't able to reproduce this, let me know if you still are getting the error on the latest version.
