Similar problem for me.
Every project I've wanted to do, there's usually some technical hurdle I need to achieve, and once I've achieved it, I lose interest and have something that's not even enough to be considered a proof-of-concept, let alone an MVP.
For example, there's an arcade game called Killer Queen that I loved, and thought it was a travesty that there wasn't a PC version, since it's a 10-player game that's played on 2 cabinets, and who has that many friends going to the arcade at the same time? It needed to be online!
So I decided I was going to create a clone of it. The big hurdle I needed to figure out was how to make a realtime multiplayer platforming game that kept clients in sync while also compensating for latency. My implementation worked by having both client and server keeping copies of the last 60 frames of game state, and the client would merely send their inputs and a time stamp (Really a frame number) to the server, which would then go back to the frame state for that number and re-simulate the game with that input. It would also stream the current state (It was only ~300 bytes) to other players with their inputs, which would also do a similar re-simulation.
I even made it mostly cheat-proof. There's no hidden information (All players see the exact same screen), but I figured a modded client could simply see what other players have done, then send inputs with time stamps in the past to put themselves into an advantageous position, but I prevent that by making the server reject inputs older than 250 ms.
But...after getting all that working, and basic platforming working...I got bored. Never touched the project again.
EDIT: I've got another game I worked on and actually got to the MVP part, but it needs a heavy refactor and I just haven't bothered. Mainly because I hate writing and testing front-end code, and I feel like I've already written it once and don't want to write it again. I haven't bought a domain for it yet, thankfully. I'm going to insist on a .game domain for it, which is like $400/year.
