Steps: How can we find the bug ourselves? Sims go to workout on treadmill and won’t stop unless I cancel it. Then, there is no workout moodlet.

Did this issue appear after a specific patch or change you made to your system? Yes
Please describe the patch or change you made. The game automatically updated 2/2/2021 when I launched the game

‌

this is a brand new save game I created 2/2/2021 after my game automatically updated. I have downloaded anything from the gallery in this game. I’ve also never dealt with this issue. I tried repair game and making a new sims 4 folder, no changes. If I tell the sim to workout, they will workout continuously for hours without getting fatigued or getting some other workout moodlet. 

It could be a build mode bug; I went into build mode immediately after the starting the game. I can start a new game and see.
