Spent the day today trying to troubleshoot why I could not create a restore point in Windows 11 Pro. Wasted the day really. Anyhow task was to troubleshoot what could be causing this failure resulting in a system restore error. Suspects included Opencore bootloader, Highpoint raid card and software, MacOs hidden nvme drive, and just good old corruption. Along the way discovered there was an OpenZfs driver installed in my windows/system32/drivers folder. No idea how that got there as I certainly did not install it knowingly. Did a lot of my trouble shooting with an AI to try to figure this out. Tried creating restore point with drive disabled, raid driver device disabled and lastly OpenZFS driver removed. That did the trick at the very end of trying this and trying that to finally have success. So if you are having trouble creating a system restore point in windows check to see if you have OpenZFS installed as a system driver because unknowing to you it might be and the cause of your issue. At least it was for me.
Note: Would go into more detail of everything I tried though I killed the day trying to solve this and out of time with so much to do!
Thank you.
