That could be the issue but check my instructions in this post, also make sure you’re not making my mistake as well which was I was renaming and typing .bin at the end but windows automatically does that for you atleast windows 11 was for me. Turns extensions on to make sure, by default showing extensions is usually off it’s in your settings google how to do it.
Then if your not making the same mistake I am follow my instruction to the letter in this topic and it should work (again yes I used a 32gb card maybe that’s your issue) :
