I was able to solve this issue by the following steps:

  • From Windows Event Log (Application Log) I learned that access for these two applications where blocked by SRP rules:
    …\AVAST Software\SZBrowser\3.55.2393.607\SZBrowser_crashreporter.exe
    …\AVAST Software\SZBrowser\3.55.2393.607\SZBrowser_autoupdate.exe"

Then I create a new exception rule for both applications.
After as restart of ASZB I can enable Bank Mode without any issues.
