My issue with sandboxie is when trying to log into a google account with two factor authentication-- in my case a security key-- sandboxie blocks the window for signing in with the second factor which is a window that pops up as "Windows security, making sure its you.." I've tried the browsers without the sandboxie enabled, and it works fine. So some how when enabled sandboxie is interfering with second factor window in popping up to sign in. I get no messages from sandboxie about the issue at all.
A photo below of when sandboxie is disable, this is the second factor window that pops up to sign in:
