After an update yesterday, thunderbird v104.2 opens up as a blank window. The menus show up and it seems to download messages, but I'm unable to see any folders or messages. I've tried deleting the "global..." file, I've uninstalled and reinstalled an older version, and nothing is working for me. I've read other threads about this issue and tried the solutions, but have not found one that works for me. I'd appreciate any new ideas. I'm running on Windows10 thanks
