Question Can't read messages in Mozilla Thunderbird and the message "File not found" appearing instead.

[aor999]

I installed Thunderbird 91.2.0, and located my old profile, however when opening Thunderbird, I can't open my messages, writing "File Not Found".
How to solve this problem?

This won't solve the problem, as this isn't the situation I have.

I receives mails to the inbox, but when opening it writes "File not found". Also, the folders are missing despite the local directory is correct.

How, specifically, did you go about moving your old profile into the new installation? List every single step of the process you used.

After installing Thunderbird, open profile manager, creating new profile in D: drive, opening and closing Thunderbird, than copying the old profile content into the new profile.
I tried lots of other methods like moving one of the default profiles to the folder of the new profile and etc, without success.
