For some reason this only happens with Unity 2020.3, Unity 2019, 2021, 2022 works just fine.
This happens whenever i try loading the URP template, or built-in variants.
Ignore the progressive light-mapper error. It inst the issue, its the ones above it.
Bumping this thread as I am having a similar issue, have you found any workarounds?
Edit: Some more digging and I found this post Empty Error on Unity Linux which contains the answer of setting an environment variable. I put it in the ~/.bash_profile and didn’t encounter that error anymore
