Wood Filler to Repair Stripped Screw Holes in Door Frame?

I have a problem with a wooden dutch split style lower door. Because it goes into a laundry area, I have had a problem with the door hinge on it coming out of the wood door frame. The metal anchor screws have been coming out about once a year and I've used a repair plate on one side of the door trim to firm up the hinge against the wood to create a tight installation, once putting the metal anchor screws back in.

However, I've had to use more than one type of wood putty/wood glue to replace the holes in the frame due to these screws coming loose over time with repeated wear.

I need someone with some woodworking expertise to recommend a wood filler product that will be durable enough not to crumble or disintegrate in the door frame so that this doesn't keep happening and I won't be frustrated with yearly repairs. I've tried at least 3 kinds. Is there any kind of industrial wood with epoxy type filler on the market available anywhere that I can buy?
