My email app crashes when trying to open a forward fwd email draft with my Airplane boarding pass

iPhone 11pro, latest update software.

So I wanted to forward email I got from my travel agent but app crashed.

Now fwd email draft is visible at the bottom of the screen and when I try to open it, it crashes the app.

I opened email normally on my laptop and forwarded it and then deleted it. I deleted it on my iphone to, deleted all the drafts, sent, outbox, deleted emails…yet fwd draft is still there at the bottom of the screen?

can anyone help?
