It seems like there’s some invalid code added in your theme files, most likely in your main-product.liquid so try searching it there and if you still can’t find it then share your collaborator request code in private messages so I can help you out in removing it.
Please go to your store admin > Settings > General > Store defaults, click ‘…’ next to ‘Currency display’ > Change currency formatting and check and remove if you added ${{amount}}, please remove ‘’ and ‘’
Please go to your theme > edit code then search for the code from my screenshot below in “main-product.liquid” file or “product.liquid” file. After you found it, please share with me the screenshot from your end then we can provide you with a suitble solution.
