Trouble running Humann 3.5 after update from Humann3

Hi there,

We have recently updated our Humann version to 3.5 on our conda environment in our cluster. Unfortunately, although it works smoothly for the person that performed the installation, I keep on getting the following error message:

I would highly appreciate it if you could direct me to where this problem might arise from? Is there a specific file you believe I should inspect?
I have also ensured that I have adequate permissions to the humann-3.5 folder (r/w/x).

Any insight you could provide will be much appreciated!
