Wont accept my payment method. There is a pending charge that Apple hasn’t completed yet. There is not an unpaid balance on my account, just the pending amount. What gives?

I’ve been using this payment method with no issues. I try to download a free app from app store, says to update payment method. I check info, all is correct. I check purchase history, I notice a “pending amount” so I check Venmo account, and it shows receipt for purchase. I also received receipt from Apple showing purchase. Why is it still pending in my account, and is this why it wont accept my payment method?
