Unknown timezone "US-Eastern" in "xxx". Treated as 'floating' local timezone instead:
After receiving an iCAL calender vent, Thunderbird Lightning/Calender shows the following error on the error console:
Lightning: Unknown timezone "US-Eastern" in "xxx".

My timezone is Europe/Amsterdam. Version: 78.8.0 (32-bit)
What is the problem? Is the problem at my side or is it caused by the calendar event generator? How to fix this problem?

wikipedia has a list of valid names https://en.wikipedia.org/wiki/List_of_tz_database_time_zones
I do not see US-Eastern listed. I do see US/Eastern but it is deprecated in favor of a whole host of America/[City name] literals as states make their own decisions on daylight saving I assume.
So I am guessing is is a non standards compliant ICS file you have received. But I am not an expert on ICAL or ICS.
