The last one was Descent Into Avernus. I hated how they've fired Mike Mearls. Tasha was the first 5E product I didn't buy and hasn't bought anything since then. Our group switched to Forbidden Lands later on.
Even when I still played 3.5 (I haven't touched D&D since as player/DM, am touching 5e now as a publisher) I only ran homebrew modules. So my answer is never - I have never ran a WotC adventure module in my entire life. I did run some TSR modules back in 1e/2e days, but I started homebrewing back then, and subsequently never purchased another paid for module. I have written, play-tested and published modules myself, but haven't touched a published module that I didn't homebrew in the first place in nearly 30 years.
Last one I DMed was the TftYP version of Hidden Shrine of Tamoachan which was so bad I haven't run another WotC adventure since. It would take me less time to do a dungeon from scratch than to fix the problems in most of these products.
Last one I played was Rime of the Frostmaiden. DM did a good job but the adventure was just okay in my view. All of our characters were parodies of Will Ferrell characters. I played Icewind Dale, based on Chazz Michael Michaels from Blades of Glory.
Most people don't even know of it. But it's a WotC adventure module. Part of the "Beyond Icespire" trilogy. It is the third module that follows on after Icespire Peak from the box set. D&D Divine Contention for Fantasy Grounds
Just a polite request not to use acronyms for module names, there are so many that I find about half the time I have to stop and research to figure out what people are talking about when they only use acronyms for the titles.
Earlier last year, I began working on revising Reavers of Harkenwold in order to revitalize a return to 4th Edition using only Essentials as an OSR-style game. I will be returning to that as soon as I get settled into our new home in Washington.
I am about a quarter at most through running Princes of the Apocalypse in my one group. My other group is about to start Shadow of the Dragon Queen. The former group is normally just official adventures, and the latter mostly just my own, but every few years I do run something official for that group - the last time was Out of the Abyss, so it's been a while.
