It's very likely due to the Unity 6 engine upgrade.   Can you send us your log files and we'll take a look at it right away?  They are located here:
%USERPROFILE%\AppData\LocalLow\Eromancer\pure-onyx
You can zip the folder and email it to us at eromancergames@gmail.com

Hey again -- checking in to see if you could send over your logs so we can help solve the issue :D.
