Can't get the oven light cover off
The two Phillip screws you clearly see hold the thermocouple for the temperature gauge. The two that look like rivets are probably screws that need to be removed with a socket or nut driver. Turn off the breaker for the oven. Verify oven's off by turning it on... the light's out so you can't use that. Remove those two screws with a socket or nut driver and pull out the element just enough to give you clearance to remove the light cover. Be careful not to pull out the element far enough to disconnect it from the wires behind it. Once the bulb is replaced, put the element back in place. good luck.
