Accidentally removed environment and I can't recreate it

I’ve taken a several year hiatus on my python learning but recently I decided to fix a project I had started awhile back.

I was trying to manage my environments in Anaconda Navigator (it’s old, v2.3.2 - and I’ve been having issues getting it to update and have tried many threads). It listed two environments (in addition to others I have): one ‘quickCue’ and the other ‘quickCUE’. I knew that my project was using the ‘quickCUE’ environment, so I decided to delete the quickCue environment to avoid confusion going forward. After hitting “Remove”, Anaconda deleted both environments.

No, I didn’t have any backups.

Then, I was trying to recreate the environment and clicked Create, and typed quickCUE. But there’s no new environment being created and the log viewer shows:

raise CondaEnvExistsError(f'Conda environment {ref} already exists')

I do see a folder named quickCUE in C:\Users\Me\Anaconda3\envs\, but it just contains a few .conda_trash files in subfolders.

Can I safely delete this folder and try recreating the environment again? I had just finished fixing my program and was going to try to install pyinstaller to make an executable…

(And yes, I plan to update everything, conda, python, etc., but only after I make my executable because I don’t want to hassle with fixing dependencies etc. until I have a working executable.)
