    I am also having the Windows 10 crash issue with latest 10.11 beta. How do I switch to Apple hypervisor?

    The issue I had with Windows freezing when switched to Apple Hypervisor was that Teams would open and then freeze, I read in another post that this was occurring due to accessing the camera, but this was related to an iMac (I'm not using an iMac). Anyway, I disabled camera, booted and freeze occurred, I "paused" and then "resumed" and was able to quite Teams and everything seems to be ok (an hour and still working). It does seem a little sluggish though.

    In VM open Configuration. In Hardware tab select CPU & Memory. Open Advanced Settings and Hypersisor Combobox appear.

    Same Problem. Just upgrade to Big Sur Beta 5 on my iMac (2017). System crashes, screen went black and restarted.

    Big Sur Beta 5 is crashing under OTHER circumstances. I have not run Parallels and it is crashing within 30 seconds of logging in. Safe mode is the only way to keep it running

    Same for me and I can't change the settings as it wants me to start the Windows 10 VM and shut it down properly. Unfortunately, I can't open it to shut it down.

    I have the identical problem as JamesB34 describes. Was working fine on Beta 4, updated to Beta 5 and Parallels crashes the Mac (MacBook Pro 15", 2017) when opening a VM. For some reason, Parallels does not recommend using the version in the Apple Store if you have the version downloaded from them.
    This could be a problem with Big Sur, not Parallels. Excel also crashes when opening files.

    To change the Hypervisor to Apple was a bit tricky ...
    As my VM was in suspended state and furthermore obviously in autostart mode, I never got the opportunity to stop it in the actions menu, not to mention any chance to switch to the Apple hypervisor before the system crashed ...

    My workaround:
    I installed the Appstore version, shut down the VM, switched off the autostart mode (which I never deliberately activated) and then installed PD16 again. Now PD is back to work without any speed issue as far I've noticed up to now. At least in such way we've won some time until Apple/Parallels will release a bugfix.

    My VM was also suspended. I also couldn't change from the Parallel's Hypervisor to Apple, as I needed to start the VM to make configuration changes, and my Mac crashed the moment I tried to start the VM. Customer support gave me the following method to change the Hypervisor type without starting the VM, which worked and allowed me to use Parallels 16.0 on Big Sur 5.

    1. Locate the virtual machine's file as described in this article: https://kb.parallels.com/en/117333
    2. Right-click on it > Show Package contents.
    3. Inside you will see a config.pvs. Right-click config.pvs > Open with TextEdit.
    4. Inside of it find (CMD+F) the following part:
    <HypervisorType>0</HypervisorType>
    and change it to
    <HypervisorType>1</HypervisorType>
    Save the changes.
    5. Run Parallels Desktop. Run the virtual machine. If prompted to reset the virtual machine, do it.

    This worked for me. My VM was suspended so previously mentioned solutions did not work. Yours worked like a charm. Tx.

    Same issue as everyone else. Kernel panic 100% of the time, solved by switching from Parallels to Apple hypervisor. I don't know what that means, but it works now.

    The solution worked for me as well but also not able to get Internet access in the VM.
    Any workaround for this. I did reinstall PT.
