Avast wont run Brave in Sandbox

Hello,

Hoping for some help with a reoccurring issue I am having.

I use Avast premium and am having issues with sandbox not running browsers.

I have rest my PC a few times because of it. After reset and fresh install the sandbox will run Brave browser without issue. At some point, maybe after restarting, Avast sandbox will not run ANY browser at all and I am forced to use Avast secure browser instead.

I really want to run Brave via the sandbox as I feel most protected that way.

Any ideas how I can fix the issue?
Thank you.
