I tried to rebuild everything again = xLODGEN, TexGen and DynDOLOD. Got the exact same error with DynDOLOD again.
Edit: Here are new logs, if that helps: https://ufile.io/tn9aheqq
Edit 2: the error shows when this window appears ↓
Today I updated everything to latest version Alpha-181.1, followed the installation instructions
Edit: Been using Aplha-180 until today, never encountered this issue

This is the last message. Zip file provides all the logs. I don't know how to resolve this.
