Cannot boot into Bootcamp in latest Catalina Patch

I installed the macOS Catalina 10.15.7 Security Patch (19H15) today. I can't boot into Bootcamp anymore not even by holding option/alt, in that case only macOS drive pops up.


I've been using windows 10 just fine until this morning when I booted into macOS and then installed the update.


I've never had these kind of issues. I have tried searching for the same problem but I can't find recent answers.

MacBook Pro 15″, macOS 10.15
