After we looked into the situation, we found the problem with the search form comes from the lack of the necessary code. We feel terrible about this mistake and regret that this error slipped past our quality processes. We are taking this incident seriously. Once it was discovered, we took appropriate measures, and in our next update, it will be fixed.
In general, this issue will be fixed in the next update, but if you want to be able to use the product search now, you need to disable the “Combine JS files” option that is in Theme Settings -> Performance -> JS.
