Hi Thunderbird is crashing with error message: expected value at line 1 column 1 Error message in crash dialog box: " Thunderbird Crash Reporter Thunderbird had a problem and crashed. Unfortunately, the crash reporter is unable to submit a report for this crash. Details expected value at line 1 column 1 Restart Thunderbird | Quit Thunderbird " troubleshooting so far: * How often? periodically (sometime within minutes of loading, sometime hours). * uninstalled, rebooted, reinstalled Thunderbird (using winget) * created a NEW profile (have to re-download mail / folders ... taking day(s?) ... since when I walk away and come back hoping download has finished but it has crashed) ... not sure when it will get caught up ( main mail file is huge (20+GB) ) * tried: accessibility.force_disabled changed from 0 to 1 (found suggestion in a google search) * tried: troubleshoot mode (even though I don't use any add-ons) * I use multiple mail accounts (although currently I'm only using main one, trying to isolate problems) Thanks for help.
