Windows 10 64, insider build on HP Pavilion x360 Convertible Intel 7.

App keeps crashing and forcing quit.

I found a fix for Windows Insider builds. A registry key that determines whether legacy filter drivers are loaded had its default value changed to disabled in Insider builders. You can easily revert this change by following the instructions here: https://docs.microsoft.com/en-us/windows-hardware/drivers/ifs/blocking-file-system-filter-drivers.

This started happening to me once I upgraded to the Windows 10 Insider builds (build 170xx). Lima is now unable to mount the drive (L:) and the app eventually fails.

Exactly what is happening to me, any solutions?

My registry editor doesn't show the IoBlockLegacyFsFilters registry key on HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\I/O System syntax, I tried creating it by adding a DWORD value but it wasn't successful.

Running the elevated Command didn't show that I have legacy filter drivers loaded

The IoBlockLegacyFsFilter key won't exist at 1st. Once I created the key (DWORD) and rebooted\reinstalled Lima, L: mounted fine. There's still been the odd app crash but I can access my Lima drive and files just the same as before installing the windows 10 insiders builds.
