Please help me solve the problem. For several days now, we have had difficulty adding products. While adding products, the save and save and exit buttons keep spinning until the server sends the message "A server error occurred, some tabs could not be loaded." This happens irregularly on various computers. . Contacting the service center did not explain anything, everything works as it should. Therefore, the website directed me to this forum for help, hoping that someone here will solve the mystery of why this is so, and I am asking for help.
I am attaching some screenshots and error logs
