Honestly same but mine won't even start new projects either. They stand their with the 'cant walk over there or interact thought bubble'. Normally 1-3 projects were able to be started, 1 could resume; but after the initial 1-3 projects, they stand there, unable to sit. I tried having them sit onto the surface first, but no luck, they either do the thought bubble like something is blocking them; also tried the cheat to teleport closer or somewhere else, again nothing. Eventually this started to effect the other skills and interactions. Baking skill/cooking: wouldn't be able to interact with food unless it was to grab a serving. Tried to decorate some baked goods I made, and the same 'cant walk or interact' thought bubble. Even moving the object into various spots doesn't help. Its effecting knitting, but also other interactions and skills. There reached a point where my sim could only build snowpals and snow angels...
