Smarter people than me can answer, but I had two similar issues before. 1) I added nofail to fstab because in my situation it wasn’t finding a certain drive and getting stuck, and 2) windows fastboot or hybernate had somehow made drive locked or appear dirty to linux

No I realize that, for me it was stuck on a windows partition , which was irrelevant to Linux running. It sounds like it found some corruption and wants to do a full disk check. Or maybe their is a hardware fault arising.
Others may have better answers for you.
