Error 2: Incorrect indication for plugins' available updates, incorrect versions named, and failure trying to update

• Furthermore, suddenly all my installed plugins now have the green dot notification that they have an update, which they didn't have before installing the new version:

• Trying to update any of them opens the update prompt, where noticeably the versions are incorrect, but in a specific way:

Details

• All the plugins show that they have an update, specifically from "version 1.20.0" to whatever their actual current version is.
• Trying to do the update, it fails with an error message. Looking at the logs, this exception is logged:

I can confirm the plugin update issue

[cibere]

Error #1 is due to a change in the behavior of python plugins and the fact that I haven't gone through and updated my plugins yet. (In some of my plugins like the rtfm one, I did something which is technically not the way I was supposed to do it, and now the thing I did no longer works as expected).

Error #2 is due to a bug that was introduced when we synced the versions of the default plugins to flow launcher itself, which should go away in the next couple of days.
