When I tried to open windows via bootcamp my Mac first showed something like “your computer restarted because of an error” and then a prohibition sign. But now after I restarted it with command + R I open reinstall macOS it shows two volumes: bootcamp and Macintosh HD, bootcamp is locked and Macintosh HD is not mounted. So is there some way I can reinstall macOS without losing the data?
MacBook Pro 13″, macOS 11.3
Ok, here's how I resolved the problem: I launched Mac in startup manager chose the disk "1" (which is the one where my system is I think, I don't even remember why is it not on default Macintosh HD) and for some reason the mac just launched normally reporting that "a third party kernel extension was preventing the machine from successfully booting".

Also it was first time when I tried switching to windows after installing the last Big Sur update so maybe it’s somehow related to it, if it’s of any importance
