Nothing happens when changing the code.

CodePudding user response：

Looks like a plugin conflict. You should uninstall plugins one by one to see which one is causing the problem and you should probably start with stm-post-type plugin.

Hope it helps

CodePudding user response：

Update the stm-post-type plugin to 4.8.5, this is solved there.
