If you find that OpenZFS is crashing everytime you boot Windows, you can remove the kernel extension part.

Enter the recovery CMD shell - you can use boot media as well

When booting, once you get to the spinning dots part - turn off your PC - either by holding power button for 10s, or cutting power.
Doing that 2 times in a row, Windows will ask if you have boot issues.
Enter Troubleshoot, Advanced Options, then Command Prompt.

Remove the driver

Navigate to your hard disk, which might not be C: during boot command console. Change drive letter, and issue "dir" until you recognise your disk.
cd into Windows\System32\Drivers
delete or rename openzfs.sys
exit command prompt
use menus to boot normally.

If you get access denied when you want to rename the drivers (fileowner is trustedinstaller)

take ownership (current user) of openzfs drivers: takeown /F \windows\system32\drivers\open*.sys
extend permissions (ex user administrator): icacls \windows\system32\drivers\open*.sys /grant administrator:f
