no columns in column view when exporting

When I export a file and try to navigate to the folder where I want to save it, I select the option to view as Columns. However, there are no columns. When I select the drive I want to use, all I see is the root directory. There are no columns and no way to navigate within the drive.

When I registered for this forum, there was also no option for Big Sur. I’m wondering what other issues Audacity is having with the new version of MacOS. This is not the worst problem, but it’s not a good sign, either.

using 2.4.2
