System crashing after one ui 7 update

[Rockstart]

I recently updated my galaxy A53 5G to Samsung's latest one ui 7 update ever since I updated my phone the system has been crashing and the phone gones off and bring one ui optimising apps then goes on again. The system crashes almost everytime the phone goes on. What could be the possible solution to this problem

My wife also use A53 her phone runs smooth no problems so far. Maby you can factory reset the phone and see what happens.
