Basically, the flow works for one-time meetings and the first time a recurring event happens, but not afterward.
No errors but also no log that the flow even ran.

The trigger "When an upcoming event is starting soon" wouldn't support the recurring events except the first time a recurring event happens.
If you want the function to be supported in trigger "When an upcoming event is starting soon",
I afraid that there is no way to achieve your needs in Microsoft Flow currently.
If you would like this feature to be added in Microsoft Flow, please submit an idea to Flow Ideas Forum:

I do think this is a big though and not a new functionality, this should be supported by working as a core functionality
