Windows 11 - Can't open any app in Sandboxie 1.4.2 Plus on security higher than default

[bogdan.lazea]

Using latest version of Windows 11 PRO and Sandboxie 1.4.2 Plus.
For some reason any attempt to open an app in a sandbox with security higher than Default fails like in the screenshot attached.

For example trying to open Notepad++ and then Firefox with no addons or apps fails as seen in these logs

If I don't terminate that Start.exe hanging (Screenshot 01.jpg) app I get lots of messages like in Screenshot-02.jpg.

Can someone help with this?

Please try the newest build 1.5.2

No luck, tried 1.5.1 (1.5.2 wasn't available, maybe typo).
I got the output of trying to start firefox two times in hardened sandbox (see attached picture)
If I leave it running I get infinite Start.exe error (6980 and 31240): SBIE2204 error

Uninstalled using Revo and installed fresh copy of 1.5.1.

Problem is fixed with version 1.5.3.
When I installed Windows 11 OS fresh copy, install sandboxie non portable, but in settings put the location of sandboxes into C:\Users\<user>\Sandboxes folder. Then after deleting Default sandbox restart your PC.
After that I installed my Bitdefender Security Suite.

Now Windows 11 and Bitdefender work as expected, and I am able to create Hardenened Security sandboxes and open Firefox inside.

This ticket can be closed,
Cheers

Hey there! Many people're having trouble with Sandboxie on Windows 11. It's definitely frustrating when things don't work as expected, especially when it comes to security.
Have you tried reaching out to the Sandboxie team for support? They may have some suggestions for troubleshooting the issue. In the meantime, it might be worth checking to see if there are any updates available for Sandboxie or for your system in general. Sometimes software updates can resolve compatibility issues like this.
You can also check out info on the windows 11 pro product key for a possible solution.
Hang in there, and I hope you're able to get things up and running smoothly soon!
