Output directory could not be found. Will only publish to desktop.

I am using 21.0.8 on a Mac running Big Sur 11.5.2. 

The problem I am encountering is with files that worked previously as well as new files. I am creating html5 ads and when I go to publish, I get the error that says "Output directory could not be found. Please update and try again." Initially, I thought that I either had moved the folder I was publishing to or I had a character in a file name that isn't allowed. I have double checked both of these things and didn't find anything wrong. I can publish to my desktop but the moment I make a new folder on the desktop to publish to, I get the same error. I have even tried naming the file and the folder with just one letter in the hopes that it really was a naming error I was missing. It did not work. I would prefer not to publish everything to my desktop as there will be a lot of files that I need to keep organized.

I have cleared Animate's preferences and uninstalled and reinstalled it. Any suggestions?

Thanks
