SBIE1222 Error with security token: [C00000BB / 35]

Question

Greetings! I'm running Windows Insider build 18908.rs_prerelease.190524-1658 
 OS: Windows 10 Pro N 64-bit 
 Antivirus: Anti-Exploit and Windows Defender 
 Affected programs: All of em 
 Sandboxie: 5.31.1 64-bit 
 
 Trying to start any program in Sandboxie results in 
 SBIE1222 Error with security token: [C00000BB / 35] SBIE1222 Error with security token: [C00000BB / 36] SBIE2314 Canceling process Start.exe 
 Have tried creating a brand new sandbox and the same thing happens there. 
 
 Any ideas?

Hi John, 
 The latest supported Fast Ring (Windows Insider) version is 18362. Anything newer than that will most likely trigger issues. More info will be posted here SBIE BETA VERSIONS (including any future fixes)
