This happened after a Win10 update and caused a PC to auto reboot overnight. User came in and tried to start Thunderbird and there was nothing there. Here is a screenshot of what it looks like when Thunderbird opens: https://i.imgur.com/CX9QOma.png What's weird is, if you go to the address book tab, the email addys are there and if you search for a contact or a keyword in the search bar, it shows the messages. But there's no accounts showing at all. I did some search on Google and I haven't found anything that helps so far. The closest I came to what I was hoping was going to be a solutions was this: https://support.mozilla.org/en-US/questions/1402124 But it doesn't appear that the JS file is corrupt because there are none of the 2 other JS files mentioned in that solution that shows the pref.js file to be corrupted. But if I open that JS file, I get this error: https://i.imgur.com/JAv908Y.png So I'm not sure if it's corrupted or not? I'm at a loss as to what to try next. I've tried re-importing that profile and I get an error when I try that, so I'm not really sure what direction to go next. Any help would be greatly appreciated. This is the most current version of Thunderbird (128.9.1esr)
