SBIE2101 Object name not found

Hi All

New to the forum and sandboxie

Installed sandboxie 5.33 3 (64bit) on my windows 7 machine all updates done its a Dell precision t1600.

Firefox and thunderbird seem to be working but I can't get windows explorer to run

Get the following errors:-

SBIE2101 Object name not found: \Sessions\1\BaseNamedObjects\ISWWH_BEACON@27e0@EFR-controller, error CreateEvent (C0000022) access=001F0003 initialized=1
SBIE2314 Canceling process explorer.exe [10208 / 7]

Does not matter how i try to start explorer, tried right click (RC)->default box->run windows explorer, RC->run from start menu, RC->run any program->explorer.exe all give the same errors, tried enabling drop rights as my account is admin but no change.

Tried disabling AV (Avast 20.2.2401 (build 20.2.5130.565)) and ZoneAlarm Free Firewall version: 15.8.023.18219 Vsmon version: 15.8.7.18219 Driver version: 15.1.29.17237.

None of the SBIE2101 errors i came across on the forum seemed to match my code.

So if someone could tell me what i'm doing wrong I would much appreciate it.
