POS Crashes when customer tries to tap before we click charge

[TupiCoffee1]

Hello everyone, 6 months ago our square POS started to act when customers try to tap before we finish putting all details into the cart and click "charge" then gives us an error and it keeps doing after that. we always have to restart the POS before using Apple Pay again. any ideas how to fix it?!
