After updating thunderbird a little week ago maybe - the program began to shut down suddenly - several times. But yesterday there was no acces to mails, folders.. just an almost blank screen. Only the 'headers' are visibly - you know: 'Files', 'Edit' etc. is visbly. When the program did shut down, I did not get a crash-report. It was also in a strange way, because, I could see, that TB was open, but when I did try to acces it, nothing showed up. I could only restart the computer to get access to it again. But... yesterday everything was, as I have showed in the picture. I can't see any of my mails - and actually I have 10 different accounts/profiles, so it's a big problem for me, that all old mails is gone - and the new one too... Fortunately all my incoming mails are redirectet to a backup mailadress - if I had not done that years ago, I would be really f.... I have tried to open in troubles... mode - does not help.... I tried to unplug and replug the pc - no difference. I have tried to reinstall TB - now several times - no difference... The problems began with an update - I wish I could downgrade to a version, that works well... But I haven't kept the older version... I'm an old Danish women with very little knowledge of reading and understanding complicated possible solutions - but I know how to install a program, so where can I find an older version to install, so that I can read and write an email again? Now I have to use and old gmail-account and not my usual accounts. I'm so sad... BTW: it's version 115.5.2 (64-bit) - and my pc is running Windows 11 I have asked in some forums too with no luck.
