main.log
This is my main log from my ~/Library/Logs/ComfyUI
And I have the same question as well :

I uninstall ComfyUI Desktop yesterday but when I try to install it today, I cannot fix the problem.

@FREEWHEELINGZL I can see a few errors in the logs.

This one is unfamiliar to me, which makes it seem like something is interfering with the UV configuration.

Error while loading conda entry point: conda-libmamba-solver (module 'libmambapy' has no attribute 'QueryFormat')

Do you have any UV environment variables set? If you need a little more guidance on this, please don't hesitate to ask.

The least-effort troubleshooting solution would be to reset your venv - you can do this by clicking the "All" filter at the top of the maintenance window, then running the Reset Virtual Environment option and any follow-up tasks.

@webfiltered This solution doesn’t seem to work. When I click ‘recreate,’ I get a ‘任务错误（task error）.’
I tried looking for solutions you told me on the top on other websites,I entered this line of code in the terminal.
conda install --solver=classic conda-forge::conda-libmamba-solver conda-forge::libmamba conda-forge::libmambapy conda-forge::libarchive
“You can copy this link to see the website where I solved the problem.” https://stackoverflow.com/questions/77617946/solve-conda-libmamba-solver-libarchive-so-19-error-after-updating-conda-to-23
and now it seems that there are no more Conda-related error messages. main.log
However, when I click ‘recreate’ again, I still receive the ‘task error’ message.”

@FREEWHEELINGZL We're working on the issue that's resulting in a conflict with your conda setup. We do not use conda, so you should not be receiving conda errors. Whilst resolving them may work around an issue for you, it is not the underlying cause.

@zefangfang Apologies, I cannot open MS Word docs on this device. Are you able to upload the original log? If you need to include images, you can copy and paste them directly into the GitHub comment box - they will be uploaded.

Since I can't install it on a Mac environment, I'm unable to figure out how to present the logs. It seems to be different from Windows.

My device is a MacBook Pro 16-inch, November 2023, with an Apple M3 Max chip.
