Unresponsive custom accordion and I don't know what to do anymore

I have issue with responsivity on my custom accordion (initially I used relume component), but I created one from scratch and it behaves much better, but it is still not 100%.

The problem is with desktop version. When I open it in certain size (not a full screen) and I downscale it, it responds accordingly, but if I try to upscale it, it gets stuck on its initial size (the one in which it was initially opened) and it does not respond at all.

Here is my site Read-Only: (Webflow - Producate)
