Error on VM registration

[Thomaswalker]

Hi all, I'm quite new to VM although being experienced developer. I'm working on a fresh installation of Joomla! 3.9.21 and VM 3.8.4 and I get a problem when trying to register on the frontend: I get an Error 500 with message "Layout bs4-edit not found". No matter which template I'm using, the result is always the same.
I tried disabling the Joomla registration redirection to VM, and the error disappears. But what's the matter with VM registration?
