TIL there were hyperinflation episodes in Europe during the middle age (not). You have never read a book of economic history (or even just history) right?

For the record: most of inflation comes from rising costs in the supply chain (from supply issues, resources scarcity and/or wage raises). This is where we are now.

There exists instances of hyperinflation related to debt (Weimar republic's for instance) but this was due to debt labelled in a foreign currency (basically gold in this case).
