I have recently developed problems accessing my online banking with Avast secure browser. It worked fine until about a week ago. Now I cannot access site. It still works with Edge. I have tried to adjust settings to no avail. Also when I try to open bank mode, I get a screen that has an open button which appears to do nothing.
Maybe it’s time for a clean install of the Secure Browser
Download the installer from here, https://www.avast.com/en-us/secure-browser
Download the Secure Browser Removal tool from here, https://download.avastbrowser.com/avast_secure_browser_uninstall.exe
Save your Bookmarks via the Bookmarks Manager if you have custom bookmarks so you can import them when you re-install.
Uninstall Secure Browser via Programs and Features - Reboot
Run the removal tool, reboot, run the installer import your favorites if you saved them.

Report back if that’s solved the problem or not.
Avast has offered a separate tool to totally remove the Secure Browser if the above instructions don’t work.
You can find that tool here, https://forum.avast.com/index.php?topic=230288.msg1531315#msg1531315
