genuinely cant play the game due to crashing

for context, this has been a problem for months now. 

i have an xbox series s and whenever i play the sims it is guaranteed to crash. it does not matter which save i play on or what i am doing, it will crash. none of my other games do this, only the sims. sometimes it'll crash within the first 15 minutes of the game or itll crash 2 hours into playing. i have to save every 10 minutes to prevent anything getting lost. 

lately the problem has been that ill make a sim in CAS and then ill go to play in live mode. as soon as i press that check mark, the game freezes and crashes. 

at this point, the game is unplayable. i want to use the new free content that theyve been giving out but i cant because the game crashes. i missed out on the most recent log in event because of the crashes. its super frustrating.  

** i have also uninstalled and redownloaded the game at least 10 times to try and solve this problem.
