Note: I apologize beforehand if my question lacks any necessary information. Repairing my own stuff is a new experience for me. I am happy to provide any additional information on request. If this question's already been asked in some form, I apologize. Close as duplicate, you know the drill.
I have a pair of what I'm assuming to be stripped screw holes on a newly-purchased dryer unit. I tried screwing them in initially with a power tool which I now know that was the wrong thing to do. When I try screwing in the screws manually, the screws get incredibly tight and won't go all the way in.
The holes are where the metal piece for the dryer door latches, so these screw holes are necessary. I tried using Woodmate's Mr. Grip Stripped Screw Hole Repair Kit, but there is no "back" in the holes to catch the strips, and the holes are so tiny that the strip I cut has a single row of teeth.

Questions
First: Are the holes stripped? If so, what options do I have for fixing small stripped holes on a dryer unit? (I have no way of isolating the screw holes from the rest of the unit, at least without taking the whole dryer apart)
Second: If they are not stripped, what am I doing wrong? Other than using a power tool on the first attempt of screwing them in, that part was my fault. Is this something a beginner can fix?
Follow-up: Would it be okay to fill the holes with clay or putty or even melted solder and then try screwing the screw back in before the material dries? Or is that a recipe for disaster?

Background info:
I recently bought a new dryer and forgot to mention to the salesperson that the door would need to be flipped before delivery. I decided to do it myself.
I have the door flipped and attached to the dryer unit, but in the process I mistakenly stripped a couple of screw holes using a power tool. If I try manually screwing the screws in with a hand tool, they get stuck halfway.
I'm a beginner with DIY stuff (I shocked myself that I was able to flip the dryer door on my own), so I don't feel comfortable with re-threading the screw hole with a new screw because it's a new dryer. If it weren't new or it was something else, I wouldn't care and I'd consider it a learning experience if I mucked something up. I really don't want to make things worse.
