Sandbox Mode is error

[wubang0930]

When I selected sandbox mode and set the Steam client to start in avast sandbox mode, when logging in through sam, there was an error message as shown in the above figure

When I click cancel, the Steam client login box will open, but the account and password will not be automatically entered

@wubang0930 what happens if you run SAM in Avast Sandbox mode?

This is the English translation of the error message for my future reference:
