Is it just the shower acting up?
Check it at a faucet, if it's ok there then it's the anti scald inside the control valve.
Very common to get trash in it if you did not remove the aerator on a faucet and flush out the lines before using the faucet.
Any major plumbing repairs like that stir it trash in the lines.

The anti scald valve is located inside some newer faucets. Some faucets have a balancing valve that prevents scalding. Both are a cartridge inside the faucet and are removable and replaceable from the front, knob side so you don't have to replace the entire faucet. The first thing to do is check other fixtures around the house to narrow it down to a water heater, plumbing or fixture problem.

I gotta admire a guy who knows his limits and admits it.

piece that goes into the 2 round hole as in the video.. I told him what I was looking for.. He went and got a Delta facuet box for a shower.. There was no piece in the box like the man took apart with the 2 round hoes.

He got the big brass piece that it goes into. It sure dont look like what the man took apart....

The last two pictures are of a Delta shower rough in and cartridge. Not the same brand as in the YouTube video attached to a previous post. Which is the unit that you have? If it is the delta, then the cartridge is all that needs to be replaced. They have several series of cartridges, you may have pull yours to figure out which you have.

When you open up your valve to get to the module, be careful NOT to use too much strong arm torque on it. The older Delta bodies have several soldered pieces in the back. If they get twisted, they can pull apart and you will have to remove the old body and solder on a new one. Not really an amateur job. Don't ask me how I know.

If the rough in matches that of the pictures, then google delta cartidges to find your match. It is either a 13, 14 of 17 series. Plumbing houses will have the replacements, I am not sure if box stores carry in stock or not. OTOH, if you remove and find an o-ring that is visibly damaged, torn or otherwise worn, you may be able to repair with a simple o-ring replacement.
