Hello
Additional information
Try MailNews:Logging https://wiki.mozilla.org/MailNews:Logging Module Name IMAP
Illustration and for my part Windows
set MOZ_LOG=IMAP:5,timestamp
set MOZ_LOG_FILE=%USERPROFILE%\Desktop\log_file
"C:\Program Files\Mozilla Thunderbird 128 Esr\thunderbird.exe"Save your file
Type : All files
illustration.bat
Then, click on illustration.bat, it will launch Thunderbird
.bat will open a command prompt window, this is normal
Shutting down Thunderbird will stop .bat and close the command prompt window
And keep an eye on log_file.moz_log from time to time, in real time, because, i noticed, stopping Thunderbird will stop .bat, close the command prompt window and empty log_file.moz_log
This parenthesis clarification :
https://support.mozilla.org/en-US/kb/unable-launch-older-version-profile
Some users have multiple installations of Thunderbird, each in a separate program folder. These multiple Thunderbird installations previously shared a single profile by default. Beginning with Thunderbird version 68, Thunderbird by default will use a dedicated profile for each installation of Thunderbird (including Beta and Nightly installations). This will make Thunderbird more stable when switching between installations on the same computer and will also allow you to run different Thunderbird installations at the same time.
You just create a separate program installation folder and then install Thunderbird into the separate program installation folder.

A Custom setup lets you choose the folder where Thunderbird program files will be installed
By way of illustration as far as i am concerned
I've created separate program installation folders
Thunderbird 91 (32 bits) installed in C:\Program Files (x86)\Mozilla Thunderbird 2
Thunderbird 102 (32 bits) installed in C:\Program Files (x86)\Mozilla Thunderbird
Thunderbird 115 (64 bits) installed in C:\Program Files\Mozilla Thunderbird Release
Thunderbird 128 (64 bits) installed in C:\Program Files\Mozilla Thunderbird 128 Esr
Thunderbird Bêta (64 bits) installed in C:\Program Files\Mozilla Thunderbird Beta
Since the release of Thunderbird 68 https://www.thunderbird.net/en-US/thunderbird/68.0/releasenotes
Added a policy engine that allows customized Thunderbird deployments in enterprise environments, using Windows Group Policy or a cross-platform JSON file.
