@kphauldren You probably already tried this but did you check to see it there was anything in the oven that didn't get finished? Like a cake or baked item? You'll see an option to resume that dish.
I tend to queue cooking options when I'm working on the cooking, baking and gourmet cooking skills and sometimes when I do that, particularly when a dish goes in the oven, they won't wait for the first one to finish completely before moving to the next dish in the queue and then everything stops because they didn't finish the first dish and remove it from the oven. What they do in that case is exactly what your sim appears to be doing. Or if another sim in the household started a dish that went into the oven and thanks to the hidden thirst trait decided they needed a drink of water and walked away to get one instead of finishing the cooking action.
And did you try clicking on the what you were cooking, not the stove, the pot on top of the stove to try to resume? You should get a resume dish option then too. I can't tell from the picture exactly what you are cooking though so I'm not sure the dish is one of those where they do the prep on the counter, start the dish on the top of the stove and then pour it into another pan to finish cooking in the oven.
Is there another sim in the house, either active or an NPC, that may have decided they want to cook something and it interrupted your sim and now that sim has taken over the stove preventing your sim from getting to the stove? Had that happen but it doesn't occur very often. DU roommates can do that and you never know sometimes.
And finally, if you have DU, have you added a mod called "allstovesmod"? That mod affects stoves grills and cauldrens to allow them to be used in a dorm. I have no idea if will affect anything on a residential lot, but it may. That mod appears to have been broken by the latest patch so removing it or updating it may fix your problem if you have been using it.
