I am also having this picker interaction issue! For me the issue started when I downloaded the Lovestruck DLC a few weeks ago. The objects I'm having issues with are ones that are supposed to have interactions added by the Lovestruck DLC in the pie menu when selected. Like the OP said, it happens with loveseats/couches/benches (I think specifically when 'watch sky together' is available for the active sim), but also with radios when the sim can 'ask to seductive dance'. I have seen it affect a few other objects like picnic blankets but since I don't use those very often its been a while since I've had an issue with one. I've had the error occur with monogamous sims alone in their house and with multi-partnered sims at social gatherings with several romantic interests.
Its odd because everything works as expected about 2/3rds of the time, but then I'll select the same object I had interacted with a few minutes prior and it will suddenly throw a LE and the interaction pie menu will only have one or two of the usual choices. I tested with and without mods and got the same error at approximately the same frequency either way.
I've tried everything except the bugfix mod suggested below so hopefully that will do it! I just wanted to second this issue since I haven't seen many people bring it up. I've also never really had an issue with my game that wasn't solved by the usual first line troubleshooting and repair stuff so im hoping someone will come up with a fix!
Also, I've copied over and attached the LE summary reports from the last time I played, in case that would be useful.
This is so interesting. For my save it's literally every interaction with sofa/loveseat ever that the LE occurs and I don't experience any other missing interactions/issues. Interestingly, my older save files operate like yours, where it's every once in a while but not every time. My newer ones are unplayable because it's every time. This is the first issue I've ever been like "no this has totally broken my game, made it unplayable, and I can't fix it." Sucks!
I will say uninstalling Lovestruck like M0fak suggested 100% fixed it for me so it's definitely some sort of issue with specifically Lovestruck, at least my issue and what sounds like yours. I don't believe it's mod related because my game, without Lovestruck, works completely fine, but who knows. I'm playing without LS for now because I simply refuse to let my 12-gen legacy go LOL so maybe try that if it's super annoying, at least until we maybe one day get a fix.
