It sounds like your gas/air mixture needs to be adjusted. The flame should have just the slightest amount of white, at the very tip. The rest should be evenly blue. There is an air vent adjustment in the line to the burner, right after the gas input.

AO smith manuals
GPVH series manual
You can search the manual for FV
The FV sensor shorted because it detected flammable gas
Flammable liquids (such as
gasoline, solvents, propane (LP or butane, etc.) and other substances
(such as adhesives, etc.) emit flammable vapors which can be ignited
by a gas water heater's hot surface igniter or main burner. The
resulting flashback and fire can cause death or serious burns to anyone
in the area. This water is equipped with a FV sensor for detecting the
presence of flammable vapors, see Figure 3. When the sensor detects
those vapors, the unit will shut down and not operate. Should this
happen, please refer to the troubleshooting guide on pages 28-30.
Troubleshoot step 14-15 says
replace the FV sensor
call tech assistance number that shows on water heater
AO Smith will refer you to a plumber
I don't believe homeowner can buy these parts due to Federal regulations
The shorted FV sensor probably saved you a flash-over
The cost of 2nd degree burns from a flash-over would be astronomical.
Fortunately you're ok, and the other folk in the room are ok.
In the old days.
Two guys I knew, winter 1978 Chicago, were laying VA tile using the black mastic.
They were killed and the house burned down because of the water heater.
Main office marked the event with a memo saying they still owed money on their account.
The only company with a re-settable FVIR that I'm aware right now is Bradford White
Bradford White Defender FVIR is resettable without buying parts.

Most likely: Combustion chamber got too hot because air intake is clogged with dust, causing less air to flow upward through vent pipe ... the slowed flow of air caused combustion chamber to overheat.
What brand and model water heater?
Look at label on side of unit and add comment.
Otherwise call service tech to repair/ replace water heater and clean arrestor screen (air intake) and replace or reset parts as needed, depending on model number and brand water heater.
AO Smith, Bradford white, and Rheem are main manufacturers.
Each has slightly different repair protocol, and each gas control valve can also be different. So more information is needed.
Identify gas control valve:
