Please fix your SSL issue first. I am seeing this error:
Your connection is not private
After that, please try basic troubleshooting first. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it's fixed, you'll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
If this is not cause by a plugin, please share wordpress credentials inside a secure note so we can check further. Thank you.
