It seem that something tries to access the \FlashDisk folder early at boot. We mount it asynchronously in the new release, to reduce boot time, but this seem to generate an issue with some components that store their own configuration data there.
Can you try to set:
[HKEY_LOCAL_MACHINE\Drivers\Builtin\SDBusDriver]
"LoadAsync"=dword:0
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\USDHC3]
"LoadAsync"=dword:0
HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Wait4FlashDisk]
"LoadAsync"=dword:0
In your registry and save it?
That should load the driver required to mount \FlashDisk early during boot and this should fix the issue.
