Hi,

I believe JetPack by WordPress is the culprit here. Try to deactivate JetPack then have a check.

If this does not resolve your issue,try manually resetting all your plugins. Please refer following guide to deactivate all plugins:

If that resolves the issue, reactivate each one individually until you find the cause.

Thanks,
