System integration not responding, preventing access to Thunderbird

Thunderbird App crash

My problem is that I can’t get into Thunderbird because each time I start it up I’m presented with a window that says "System Integration" (Not Responding)" and I have no way of making progress – all I can do is use Task Manager to exit TB.

The “system integration” window first appeared a few days ago and initially I was able to dismiss it by choosing the “Skip integration” option. Today was the first time it became unresponsive. No changes have been made to the system and TB should be up to date – though, not being able to open TB, I can’t check the version number (probably esr).

I have used TB for many years and have it installed on two PCs, both running on Windows 11. It’s working as normal on the other computer.

I’ve tried rebooting the computer, to no effect. I’ve also tried to open TB in troubleshooting mode but can’t get past the "System Integration" (Not Responding)" window.

It’s been a couple of months since I backed up so I’m really hoping there will be a solution that preserves all my emails, address book and calendar.

I’d be very grateful for any suggestions.

Many thanks for this suggestion, Wayne. I’d already tried opening TB in troubleshoot mode but still couldn’t get past the System Integration window. However, you must have sent some good vibes through the ether because when I inadvertently started Thunderbird this morning (not in troubleshoot mode) everything was working as it should - the screen had a slightly different layout, but that was easily fixed. Hooray! Up to that point I’d tried starting TB a couple of times each day with no luck so I’m mystified as to why it’s now sorted itself out without any intervention from me. Perhaps the planets are aligned! Thanks again for taking the trouble to respond.
