Well, sorta.
You can say that the War In Ukraine was not natural (definitelly man-made and entirelly avoidable) and the imposition of Sanctions on a oil producing nation was not natural (it was a choice, even if the only reasonable one), plus all the increase in the money supply and decrease in the cost of debt from ZIRP which devaluated money (hence inflated the currency-denominated value of things) were also not natural.
However the effects of those things were natural consequences, and that includes Inflation, which came in via increased energy prices, increased realestate prices (cheaper debt and the rush up the yield ladded of “investment” money pushed those up) and just the straightforward devaluation of money.
However it seems that most of the inflation, at least beyond a certain point (this stuff was already happenning before the War) was not from the natural effect of those other things but rather companies taking advantage of the situation to, in a cartel-like fashion (not actually a Cartel in legal terms because they didn’t get together and agree to do so) pumping up prices in tandem to increase profits.
