Is a faulty 15 amp GFCI breaker causing my kids’ room to trip, and would upgrading to a 20 amp breaker be a solution to prevent this issue?

Hey there, I could use your input on something. Lately, the GFCI 15 amp breaker in my kids’ room has been tripping. All the electrical appliances in the room are being used as usual. I’ve inspected all the plugs and wires, and everything seems fine. Do you think the breaker itself might be faulty? What should I look out for to confirm if that’s the case? Is it safe to switch it out for a 20 amp breaker to prevent it from tripping? Thanks in advance for your help!
