Hi @kafker,
I've encountered the same issue as well. The difference is that I was following this tutorial:
Using RESCRIPt's 'extract-seq-segments' to extract reference sequences without PCR primer pairs.
It seems highly likely that is related to qiime2-2023.2. I also have qiime2-2022.11 in my conda environment, and when I run 'qiime rescript evaluate-fit-classifier' in that environment (with RESCRIPt installed), I don't encounter any errors. I recommend giving it a try with qiime2-2022.11 to see if it resolves the issue for you.
Best of luck!
