Fussy baby 😭

My 9 month old baby is kinda fussy. She tends to cry everytime when she's placed on her crib and even on her walker. She walks around the house with her walker without crying but then after several miniutes she cries so hard. Idk if it's just a case of separation anxiety but it is really disturbing and distracting. I can't even do my daily chores/activities around the house. Any tips from the mums here? 😊
