Hi @zavinator welcome to the forums!
I have seen issues on Windows where it tries to launch the engine twice depending on how you have the environment variables set. However, I’ve not heard of this for Linux before. The first error suggests it might be running the startup script twice.
What does the HOUDINI_PATH env var look like when printed out in Houdini’s python console?
import os
print(os.environ["HOUDINI_PATH"]
