If basic facts like “I have observations” are being doubted, then any case for belief in physics has to go through something independent of its explanations of experiential evidence. This looks to be a difficult problem
There are significant differences between observations in the sense of pointer positions, and qualia.
You could potentially resolve the problem by saying that only some observations, such as those of mechanical measuring devices, count; however, this still leads to an analogous problem to the hard problem of consciousness, namely, what is the mapping between physics and the outputs of the mechanical measuring devices that are being explained by theories?

That’s much more like the easy problem.
