Android subsystem is not installed

Regarding the hardware and virtualization, everything is fine (probably). Intel® Core™ i7-10510U CPU @ 1.80GHz, Modern. When I want to install Android, a window pops up with an endless loading. At the same time, I want to note that yesterday everything worked fine, when suddenly Android stopped working for me. MAYBE this is due to the fact that I reset the BIOS to default.
