Since upgrading to version 15.8.243, the bootcamp partition can only be mounted in a readonly manner. I can't seem to find anything in the FAQ or forums to help here.

What can I do to to allow it for read/write mode?
What logs would anyone need to help me diagnose this issue?

Mac Book Pro (2017): Big Sur 11.5.2, 16 GB RAM, 2.9 GHz Quad-Core i7

1 TB Flash Disk
Macintosh HD: 450GB
Bootcamp: 550GB

Bootcamp is Windows 10, fully activated and updated

Any help appreciated!
