How annoying. Did you use Migration Assistant when setting up your new Mac?
Does it happen with a brand new Electronic Arts > The Sims 4 folder?
Have you tried repairing the game in EA App?
Does it happen at any specific time, such as being on a Lot with lots of sims or maybe when doing specific interactions?
Is the environment exactly the same on the M4 as the M1 such as the same apps and processes running in the background? Same installation location?
Are you running the same macOS version on the M4 as you were the M1?
