Virtual machines failed to start, almost always on "Integrity error (0xe986ffdd/-35): NtQuerySystemInformation/SystemEx"

Hello,

maybe (not 100% sure, and no idea if related) after latest windows updates.

Full error message:

---------------------------
VirtualBox - Error In suplibOsInit
---------------------------
Integrity error (0xe986ffdd/-35): NtQuerySystemInformation/SystemExtendedHandleInformation failed: 0xc0000004
(rc=-35)

Please try reinstalling VirtualBox.

where: suplibOsInit
what: 1
VERR_UNRESOLVED_ERROR (-35) - Unresolved (unknown) host platform error.
---------------------------
OK
---------------------------

Windows 11 host, Windows 10/11 guests

Sometimes host boot helps, sometimes repeated tries to start the Guest will work, sometimes no errors for a while

Any idea show to fix. Suggested reinstall did not help....

Yellow,

Did uninstall, then installed again, seems that it helped. If the error returns I'll try to remember to post follow up.

Don't remember did I just use Repair-last time.

Please provide a VM log file. Make sure the VM is fully shut down, then right click it in the manager UI. Select "Show Log" and save "VBox.log" (no other file) to a zip file. Attach the zip here.
