Latest version has no file browser, indeed. Also, vWATCH doesn’t play well with “Output exe to source folder”, but if the .vwatch.BAs file was properly output, you should be able to manually compile it and it’ll connect with the vWATCH interface.
Also notice that vWATCH is yet to be updated to deal with new QB64 syntax features - no DIM AS Type var-list, for example.
