The newer GAS RANGES have a SAFETY switch on them that the gas will not flow if the ignitor is not functioning.
Check, your IGNITOR.
OH yes........... Check and make sure some one has not turned your gas off under the range or where it comes into the house. It could be damaged, or someone is playing a joke on you..

There should be a metal spring cip ring around the spindle of the knob which keeps it tight around the spindle on the switch. Sounds like its snapped. Compare it with one that works, they should just pull off and push back on, but with a little bit of resistance.

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.
