I can’t add a product

Hello.
I am having some difficulties with the plugin.
It is necessary to wait a very long time until the opportunity to add a product is loaded https://prnt.sc/jfeNWyMGSJ_A more than an hour has passed and I still can’t add the product, I wanted to add a product through a search on the site, but it can’t be found by name or ID https://prnt.sc/wyygwLOAkrD4

Please help solve the problem.
