After a very recent Windows Update (from 18362.10019 - 18362.10022) Sandboxie won't start.
This build is the forerunner to the 1909 October Refresh.
I have my doubts that anyone at Sophos is testing the new builds of Windows 10 for compatibility between Sandboxie & Win 10.
I am left with two options as I see it:
1: Roll back to the previous build of 10 18362 and disable Windows Updates, or......
2: Give up on Sandboxie and uninstall it (maybe forever)
Very upsetting, after using Sandboxie since the original release many years ago and having paid for a lifetime licence.
