This is likely because conda changes the prompt, which Org mode does not
expect.

I am afraid that there is no general magic solution to detecting
prompts. We either try heuristics and hit false-positives (that's what
we did in the past) or set very specific prompt and try to search it
(now). In the latter case, any changes to the prompt will break things.

What can be done is force-setting the prompt every single time babel
sends output to the comint buffer, but it feels wrong.
