I didn't drill pilot holes for the 45mm screws, only the 120mm ones (of which there are 2) and they don't spin at all.
But previously you said:
they all spin when all the way in.

this time just screw the 45mm wood screws in.
If hanging a 40" tv on ply, which I do a lot, about four screws and washers put in with a cordless drill works fine for me. I think I could easily hang myself off a bracket that way
Use twin threaded screws and decent washers and it shouldn't get loose.
I think osb might be slightly more likely to strip out but with care it should be fine
TVs are getting a lot lighter every year. I hung a plasma (50) last week that was maybe 5 years old and it was a two person lift whereas the next one was an LCD that weighed almost nothing
Are you sure that bracket is the right way round?
What did you do to them before if you didn’t “just screw them in”?
How much unthreaded shank do these 45mm screws have?
They look a bit thin to me.

I’ve just tried an experiment with a 4x50mm screw into a piece of plasterboard and OSB, and it’s solid. No spinning. See photo.
Is it possible that the screws have gone through the plasterboard and then just pushed the OSB away?
What are you using to screw? An impact driver set to a high torque setting?
