Qty button doesn't work and also add to cart button not working on mobile device.

I think I have wrong updating my Shopify or Something goes wrong when I add some app, but suddenly in product page I can’t add or reduce qty by clicking a button, only manual input, and this is what error I found

caught TypeError: Cannot read properties of undefined (reading ‘read’)
at updatePricingQty (timber.js:92:40)
at HTMLButtonElement. (ajax-cart.js:504:11)
