“conditional logic” option doesn’t work

hi, I have a problem with the “conditional logic” function. it initially worked fine, now magically it no longer works on almost every item it is set to. Let me explain: it is set so that if you select a certain accessory, then a screen appears where you can also choose the color of this accessory. This doesn’t happen anymore, even if it worked before, and now if I try to delete and rewrite the formula it doesn’t work.
