Serious error has occurred when loading my save

Thanks so much! I was able to get rid of One Drive which i felt probably was the problem and once I let the system create a new Electronic Arts folder the game did start successfully. Unfortunately, i think the old sims 3 folder just is not usable anymore because when I copied it into the new electronic arts folder and deleted the other one, the error was still happening so I will have to probably restart my legacy but that’s OK because I hadn’t got far. Thank you so much puzzle addict.
