Bug description

When I go to the "external storage" folder, and I click on a folder, the first access works, but if I click again the second access indicates an error of the mount point, it is necessary to refresh the web page to have access again

Steps to reproduce

1. Go to file tab ---> External storage and click on a folder , First access works
2. Click back on external storage
3. The error appears in a window with the following message "External mount point error There was an error with this external storage. Would you like to review the configuration of this mount point on the settings page?"
4. Refresh the web page and click on the folder again and access works
5. See video of the error. https://github.com/user-attachments/assets/9957e488-892a-42ba-852e-fc950f62d95e

Expected behavior

I expected to have access to the file again without an error message.
