Yes...I was the primary on my and spouse's tax returns for several years. I had the same problem as you did when I tried filing the final joint tax return (spouse died in September 2019). I posted a lengthy post with details (I have a background in IT, project management, business analysis, and software development) and used my knowledge from software development to theorize the scenario that TT wasn't able to handle.
Apparently, the TT administrators removed my lengthy post from this board; maybe someone did not like the traffic that my message attracted, maybe the detail that I provided in that message, and maybe even the success I had with filing the joint return with no problems using an alternate program.
