High CLS Product Page - need Ideas - shopify

Question

i started my online shop a few months back and since im not a programmer i finally reached a point where i need help.
I was trying to improve Pagespeed according to Google and i managed to get the CLS of my Index page to almost 0. - Lazyload, System Fonts, Aspect Ratio of Pictures and so on... i managed to find it all in the Liquid Code of my Shopify Store and optimize it by myself. ... ok i totally crashed the page a few times but thats what backups are for ;-)
But i have no Idea about the Product Pages.
Lighthouse can tell me the Objects causing a CLS of almost 1(!) - mostly its around 0,9 - but i looked at the code of these Objects for 5 days now and i am lost.
its supposed to be caused by the following:
main#MainContent.main-content
div.col-12.col-md-6.order-1
div.page-container.page-element.is-moved-by-drawer
...and sometimes a few more causing small numbers ob CLS
i tried diffrent Templates of my theme but no change
i googled a lot... and i mean A LOT in 5 days...
i tried many suggestions that i found while googling about this issue
i tried to find Code checkers or HTML code Analyzer but that didnt help
i tried things mentioned in this thread: Cumulative Layout Shift with Bootstrap 4 grid
i dont see the Layout shift supposedly caused by these elements
the only Layout shift i can see is somehow NOT mentioned by google - but results don`t change if i remove the app causing the layout shift that i can see. (app is called Legal Pro - needed for keeping the shop up to the requirements of German law. it injects Product data between the Price and the remaining Stock. I can not change the app, only deactivate it. But even when the app is removed, the Lighthouse data does not change. Not even a little!
i would be willing to totally replace the code of the product page with a code with less CLS but adapting complete new code to the existing pages is out of my league. I can change it but not write it. :-/
I`d be very thankful for any help. Just give me something i can google.
(and yes i know there are more issues on that page but CLS is giving me a bad Google ranking right now - one problem at the time)
an example Page can be found here:
https://besonderes-mit-liebe-handgemacht.de/collections/mannergeschenke/products/edle-kugelschreiber-von-hand-gedrechselt-besondere-holzer
the Product page code for the Page is this:
