Yah, just found that out it says.
Starting Spring from: /home/REDACTED/Documents/Evolution RTS/engine/105.0/spring

Spring failed with code:
Glibc_2.29 is missing which is non compatible with Ubuntu 18 so sadly I can not play it. Though it should work on Ubuntu 19, 16, and 20. Although I have not tested it.
But the launcher works and I even did an update. I also tested the Stable, Dev, and Portable versions, all had the same error.
