@m4zuper Strange, as this is broken at least since 26.8.0 or something related to this. Hence I thought it's generally not working an concerns every user...
Currently using 27.6.2 on Windows 10, 64BG RAM, Ryzen 7 5800X. BAS is installed at the standard location on C drive. And it happens with every project I try to add this way. Okay, it's not that issue but it's convient to add a project with just one click.
