Unable to launch any application if not run as an admin

For some reason Sandboxie stopped working recently under standard users... I am using the latest version 5.33.1 (64-bit) on Windows 10 Pro (64-bit) v1903. If I run it under an admin user, it works without issue. If I run it under a Standard User I get the following errors and the applications to be sandboxed never run. Sandboxie does open and shows a Start.exe running, but nothing from the application. The PC is NOT on a domain, it is standalone.

SBIE2313 Could not execute SandboxieDcomLaunch.exe (346)
SBIE2204 Cannot start sandboxed service DcomLaunch (346)

Any help would be appreciated.
