i cant reproduce this, what program are you using to test it?

Tor browser installed inside the box and the media player installed outside , no program gets blocked from accessing the net with classic method, and if there is a allow list the PromptForInternetAccess will still trigger but yes/no choice has no effect for any process if the box is not using WFP but network devices

It's like reported #1955 (comment) here but TOR instead of not being able to connect at all it's reversed while still reported as a denied connection in 1.3.0
The message hidden with classic UI appears in the config as
1.3.0 (5.58.0) : SbieCtrl_HideMessage=1307,firefox.exe [Tor] *
1.2.8 (5.57.7) : SbieCtrl_HideMessage=1307,firefox.exe [Tor]

Ahem... and found the problem...UseRuleSpecificity=y turned it off and now Tor box is blocked if i use ClosedFilePath=InternetAccessDevices, also seems that 1.3.0 did fix SBIE2112 issue

Only 1 issue remain

ProcessGroup=<InternetAccess>,tor.exe,firefox.exe
ClosedFilePath=!<InternetAccess>,InternetAccessDevices

Still triggers PromptForInternetAccess but this time with RuleSpecificity disabled the yes or no choice have effect but the allow or blocklist via processgroup is ignored , no issues with WFP

aaaa.... RuleSpecificity=y that makes the difference indeed, to be exact this recent change:

  • rule specificity is now even more specific a exact rule now overrules once that end with a wildcard

please open a new issue for that and explain in more detail how to reproduce

There is no need for that , with all the tries to find why the SBIE2112 error happens i forgot how blocking devices and PromptForInternetAccess work together, the tor browser is installed inside the box , if i try to use like above an allow list for it it's blocked regardless ["Note: Programs installed to this sandbox won't be able to access the internet at all." or "When this feature is enabled, programs that are installed (or downloaded) into this sandbox will never be allowed to access the Internet, even if they match the program name specified above."] PFIA=y prompting me with the choice to allow or block which works on 1.3.1
This limitation is not present with WFP which the box was using before i switched to devices to test for SBIE2112
