Sandbox not showing apps running

[avast714]

Windows 10 Home, 64-bit. Build 19042.867.
No other AV Software, only Windows built in Defender.

Avast Premium Security 21.2.2455 (build 21.2.6096.649)
Protection -> Sandbox -> RUN APP IN SANDBOX

There is no APP LIST to press CLOSE APP.
It is bugged and happens a lot of times when I test run apps.

Only way to close all programs in Sandbox is to restart PC.

Please fix.

- Other security related software installed..?
- Which AV(s) did you use before Avast..?
