If that spending creates an imbalance of money vs goods.

The problem with the COVID recovery is that goods availability declined, and as a consequence the economy would have taken a nosedive via compounding effects.

Unfortunately, flooding the market with money (which all countries, not just the US did) masked the problem long enough for supply to renormalize... but in the process ballooned the numerator while the denominator was still temporarily low.

Of course that's going to cause price inflation.

And then when supply returns to normal, of course companies are going to try to retain that new margin as profit, instead of decreasing prices.
