I think there is more than one reason for the current inflation. The supply crunch is one factor. The stimulus is another. In particular the Biden stimulus is considerably different than the Trump stimulus in that it gave the money to people who would spend it on goods and services instead of people who would just stuff it into their market accounts. This caused a demand spike right at a time when supply was unusually constrained. Unfortunately as the stimulus was known to be a short term thing this did not lead to people starting factories to make products to sell. By the time they got it running the stimulus would run out and they would be left holding the bag.
