Unfortunately, you deleted the template which, if filled out completely, would have given us enough information to begin to answer your question.
I think "btt pi" refers to https://biqu.equipment/products/bigtreetech-btt-pi-v1-2?variant=40326121980002.
That doesn't tell us what software you installed (and how you installed it), what camera you have (and how it is installed).
Please provide as much detail as possible, the more you give, the more you will receive.
