Can you, please, provide a little more information about the specific scenario causing the issue?
- Does the problem occur when you trying to open only specific folders, or does it happen sporadically? Can you make the permission tests from this help article and see whether the application has proper rights to access these folders?
- Is the FileExplorer on your page ajaxified? Can you disable the AJAX and see what the result will be?
If non of the above is the case, please, prepare a sample fully runnable project reproducing the case
and send it so we can examine the problematic configuration on our side.
