Thanks for looking at it. I have been in contact with Nogog and he thinks it's a MO2 VFS issue. I have a question on MO2 discord about it. In the meantime, could I ask what versions you are using compared to mine. I am using MO2 2.5.2, Synth 0.32.1 and Dotnet 9.0.101. I have tried re-installing all of them but nothing has helped so far. Was wondering if I should start trying different versions. I apologize if I'm being a pest.
NEVERMIND... I finally found the error. It was with Bitdefender. I had added an exception for synthesis.exe. However, all the options weren't checked. I added "Advanced Threat Defense" to the three default check boxes and now it works. For other morons like me, this is found from Bitdefender dashboard > Protection > Anti-Virus (open) > Manage Exceptions (this is where you set it).
Again, sorry for all the confusion.
