I had a problem with a new upgrade for TB and was asked by another moderator on this site to update my version of TB (128.1.1esr 64-bit) to v128.2. My version of TB did not recognize the need for an update and so I downloaded and installed TB 128.2. It successfully installed as an upgrade but in a wholly different folder under C:\Program Files\MozillaThunderbird. The previous instance of TB, 128.1.1, was installed in a different location under C:\Program FIles\WindowsApps\Mozilla Thunderbird. Under control panel I see only one instance of TB and that is the new v128.2. Under Windows Settings, Apps and Features, there are two instances of TB.

Both instances appear to be seeing the mail profile so the only thing I want to know is if it is possible and how to remove the old version of TB without losing the mail profiles. Or do I uninstall the new version and roll back? In any event I do not want to lose a mail profile with years of information.

The previous instance of TB, 128.1.1, was installed in a different location under C:\Program FIles\WindowsApps\Mozilla Thunderbird.

Simply delete the old TB program version using Windows Explorer. It will not touch your existing profile. Having said that, it's always recommended to create a full profile backup on a regular basis. https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data#w_backing-up-a-profile

Note, you should avoid starting different versions of Thunderbird with the same profile.
