Maybe you are facing this issue because of compatibility issues. So to make sure if possible, please do the following steps.
Could you please disable all the plugins and check this?
If you disable all non-related WPML plugins, switch to one of the default themes like twenty seventeen, the problem persists or not?
+ Make a backup (both files and database) for your site before updating/proceeding anything (Always a good practice!).
In your chrome browser Press Ctrl + Shift + J (Windows / Linux) or Cmd + Opt + J (Mac) before you go to this step.
Check if you see any red errors here : hidden link and let me know.
