Good thing is that since time has stopped, you won’t get your eyes burnt since light stopped travelling as well.
The scenario doesn’t really make sense as the electro-chemical activity in your brain would be stopped as well, so you couldn’t be conscious.
But if we suspend disbelief, you could say that you’re stuck with the image that got to your retina when time stopped. Which means that you couldn’t see the protagonist moving!
Also, realistically, he couldn’t even move as he’d be against a barrier of unmovable air.
I think a more reasonable interpretation is for time o have been slowed to an extreme extent: a factor of 10^6 would mean the 6 months of protagonist time would’ve been experienced as 15 seconds of bystander time, and light would be slowed down to about 1000 km/h, still substantially faster than a human can move unaided to avoid Cherenkov radiation.
To avoid friction fires, we have an Alcubierre (warp) bubble of fast space out around the protag. Let’s say about 6 inches for reasons, and with a smooth gradient between protag time and slowed time. This is also necessary to prevent shear forces from tearing up everything the protag touches.
This should handle most situations well: the protagonist can manipulate and interact with typical objects with their hands and other body parts without instantly exploding them or shearing them in half. However, humans that the protag directly interacts with will end up experiencing much more clock-time during the interaction, potentially even within the human reaction time of 250ms given a dedicated amount of attention.
As an aside, if light stopped too, wouldn’t that mean that the world would be plunged into darkness?
Photons of light reflect off of objects, and into our eyes before being converted into electrical signals by the brain and translated into visuals that we see. But to do this, photons and electrical signals need to be able to move through time and space. So if time is stopped, and light is stopped with it, none of that other stuff happens, and we all would effectively be blind. No?
