what is player lock? maybe already kwnow but just in case the players has roles and you need to put the right roles in the formation squad > tactics.
Second, maybe you must to enable some visual references that shows you were the passes goes, if you hold the button a little longer maybe change the target, you need hold the button depending how far the players are, theres a visual that can help you with that. Third, there's a help that sometimes helps that help you with the passes and shots, is enabled by default, you need to disable the help for passes, but, at least in earlier version of the game like Fifa 22 y 23 the help is really helpful, Try to disable at that time but was worste, so, well check your player roles.
about the tackles, didnt get it.
