Hi~ @Ethan,

Thanks a lot for your report and waiting.
This blue screen issue is caused by cbfs6.sys, which is an old-style drive.
We’re working on resolving it and will announce an official preview within this year.

Also, we will let you know ASAP.

Can confirm, I too got the same issue while using Raidrive when DevDrive is mounted. At first, I thought it was AMD CPU-related issues. Then after seeing this post, I can confirm. Tried mounting onedrive business drive with BSOD failure.
On the first try, it was taking forever to load after auth, next time after I restarted, after authorizing again, I got the same BSOD message as above.
