This may be a plugin or theme conflict. Please attempt to disable all plugins, and switch to the default Twenty Twenty theme. If the problem goes away, enable them one by one to identify the source of the problem.
If you can install plugins, install Health Check. On the troubleshooting tab, you can click the button to disable all plugins and change the theme for you, while you’re still logged in, without affecting normal visitors to your site.
It looks like a possible plugin conflict. You can install health check plugin which can be used in troubleshooting mode to deactivate all plugins and theme. It might help narrow down the source of the issue.
