@UEFf0rever
there are 2 errors in your log:
warning: SND: Error playing cue 1 on bank 48 [ursstream]
XACT: Invalid arg
This sound error will cause gamecrashes, please fix!
* AI-Uveso: AIExecuteBuildStructure: All checks passed, forcing enginner TECH1 AEON sal0119 to build TECH1 T1Resource uab1103
This is a warning and tells us that unit sal0119 has no build templates and the AI does not know how to handle this engineer.
It is also possible that unit sal0119 is incorrectly configured as an engineer with no ability to build structures.
At least we should check the unit sal0119 and check why its causing this error.
don't know what mod this is from - maybe a BrewLan unit.
For now, i would suggest you fix first the sound problem,
then we can continue to check / fix the engineer issue.
here is some help to configure you sound system:

Your configuration is correct if you no longer have XACT: Invalid arg
errors in your log.
