How can I analyze growth stocks with high P/E ratio and try to determine if the high ratio is justified?

Before the tech stock correction there were some stocks (still are) with insanely high P/E ratios. An example of a stock I followed is Adyen and there was a moment where the P/E ratio was over 200 (currently around 80)

How can I analyze stocks like these to try and determine if high P/E ratio is justified or the valuation is crazy high?
