Just open a new email, don’t even fill in the recipient address, but start explaining your problem to someone who is an expert at solving problems but that doesn’t know anything about your problem. Be thorough in your explanation; mention what you’ve tried and the results, talk about how the thing works, how you expected it to work, what is specifically blocking you, etc.

I inadvertently do this sometimes when opening new Github issues 😆 By the time I thoroughly explain the situation, I realise my mistake or the way I could solve/circumvent the problem on my end, so I just don't submit the ticket.
