Oven Functionality causing the main circuit to trip

I’ve been using my oven normally for bakeries , recently I’ve facing an problem with it whenever I turned it on it trips the main circuit of the apartment! This happended after switching on the grill mode, even just switching on the light of the oven causes the same.
Despite the oven not functioning I can normally use the stove without any issues!
Can you highlight what might be the possible reason for this?
Thank you!
