Support Assist Pre-Boot System Performance Check Shows Up When Trying to Boot into Bliss OS

I have Windows 11 and Bliss OS installed on an SDD on my laptop. The Bliss OS partition has I think 20 or 24 GB allocated to it. When I try booting into it, Support Assist Pre-Boot System Performance Check starts. If I abort it, Windows recovery screen comes up (the "your PC needs to be repaired" one), even though I believe I'm not in the Windows partition. If I restart, the recovery screen still shows up, unless I boot into Windows through the boot menu accesed by pressing F12 at startup. After that, Windows works fine. Haven't tried letting the Support Assist Pre-Boot System Performance Check finish, what exactly does it do? Is it supposed to show up? How do I get into Bliss OS? Thanks in advance.
