Try shutting off the propane tank. Then bleed the system. Next, only open the propane tank valve part way. See if that makes the difference. Some of the new ones have a valve sensor that recognizes when too much gas or propane is flowing and will not allow the device to spark.

I am a retired career chef, and had this one oven with choking CO in an airport catering kitchen. We had it serviced and it was fixed. It sounds like yours is not getting enough air mixed with the gas. Adjusting the gas is one thing but the venturi to the burners can partially block and unburned gas spills over. Remove the burner and venturi and boil it out in whatever you boil your fryers out with.
Are you on mains gas or propane because the jets are different.

Here is text followed by a YouTube. Possible reasons why your oven won't turn on even though the gas and range hood are working:
Igniter: The igniter is responsible for lighting the gas in the oven. If it's faulty, the oven won't turn on. You can check if the igniter is working by looking for a glow when you turn on the oven. If there's no glow, it's likely that the igniter needs to be replaced.
Wires: The wires that connect the oven to the power source may have come loose or be damaged. Check the wires for any signs of damage or looseness and replace them if necessary.
Safety valve: The safety valve regulates the flow of gas to the oven. If it's faulty, the oven won't turn on. You'll need to hire a professional to repair or replace the safety valve.
