Add vault causes a black import dialog window after several minutes

I’m trying to add a vault to a folder. The folder has a lot of content. I open devtools. Eventually the import window is all black and devtools says the application disconnected from devtools.
The black window remains open. There are no errors on the devtools console. Can you point me to a log file to help identify the failure?

I should note that this process seems to work without issue when I create a vault and the folder does not exist.

Downloaded the app yesterday.
