It appears Windows 11 KB5065797 broke my Thunderbird. It will not start normally nor will it start in safe mode.

- I've updated to latest version 144.0 - I've tried starting in safe mode - I've tried running as administrator - Thunderbird shows in Processes, and displays suspended randomly - I've restarted Windows - I've cleared cache under users\x\appdata\local\thunderbird\profiles\x\cache2\entries\

Hello, I’m unable to add additional email accounts on one of my PCs. I’ve tried everything — uninstalling and reinstalling Thunderbird, deleting cache files in AppData, but nothing works. The program keeps crashing every time.

Thank you in advance for your help, Alexis Lauxerrois

Bonjour, Je ne parviens pas à rajouter d'autres compte de messagerie sur un de mes pc. J'ai tout éssayé désinstallé réinstaller supprimé les fichiers caches dans AppData mais rien à faire ça plante tout le temps.

D'avance merci, Alexis Lauxerrois

Hi I have just reloaded Thunderbird onto my laptop after installing a new hard drive. It worked Ok until i imported an account and now get this error message even if I uninstall and reinstall.

That appears in a box and thats it.

Cheers Jim

thunderbird won't start after installation giving message that a version is already running. I end the task in task manager and it doesn't help, then restart with same erro. I tried deleting the parent.lock file from the profile and that didn't help. What next? Has anyone solved this issue?

Hello, my email service has shut down for the second time. When asked to open, a small window appears and says the system is affected by a whatever. The window only lasts for a couple of seconds.

I tried to follow the instructions as how to get my profile, but is was lost due to an internet access cut.

Hoping someone can help. regards Stephen
