Thunderbird ერთობის განხილვა

Good day, After upgrading Thunderbird to 143.0.1, I noticed that a large part of one of my local folders is missing. Searching the internet regarding this problem, I found that this issue happened last year and at other occasions. Why hasn't this problem been solved yet at it is a pain to locate and find the missing data ourself. Any suggestions to avoid this problem in the future

Best regards Douglas Noades

I get an error message when I try to update (see screen shot below). Thunderbird is on a Windows 11 Pro PC with the latest Windows updates. This has been happening for a couple of weeks now.

Thanks in advance for your assistance.

Damage of all cyrillic symbols in subfolders' (not folders'!) names occurs after update from the latest minor version 128.x.x to 136.0.

The names of subfolders in Russian (marked in a large red rectangle) are damaged now. However, their names in the upper right zone (marked in a small red rectangle) near message count are shown correctly in Cyrillic (Russian)...

Notes: 1 - Subfolder names are broken (see the 1st screenshot). 2 - Folder names are good (see the 2nd screenshot). 3 - Some zones are faded by me in case of privacy.

How to fix it?
