You can use the Health Check plugin to help you Troubleshoot. It will disable plugins for your user only, without affecting site visitors.
But before you try that, you can see if there is a javascript error, since the whole Customizer runs on javascript.

Joy, this was really helpful thank you. I have tested with Firefox on Ubuntu and the problem does not exist, I can customise my WordPress site.
I only have the problem with Safari on Mojave.
SCRIPT_DEBUG did not fix the issue.
I have identified the following Java errors
parsing the ‘sandbox’ attribute:’allow-orientation-lock’, ‘allow-presentation’ are invalid sandbox flags. attr query.js4:11269
TypeError: Argument 1 (‘target’) to MutationObserver.observe must be an instance of Node. observe wp-emoji.js:164
TypeError: null is not an object (evaluating ‘document.body.style’). onload site name:568
I could not workout how to export the error to paste here or how to paste a screenshot here so I retyped the above.
Hopefully, someone can point me in the right direction for a resolution.
Thank you for your help.
Regards
Joy

According to those errors, the problem is not in WordPress. It is in either your theme or a plugin.
Look for a plugin that has something to do with sandbox or orientation (as in the direction you hold a phone) or emojis. If you don’t have something like that, it’s likely your theme.
You can use Health Check to isolate it, if you have to. Once you know the culprit, you can ask in their support forum for a fix, or find a replacement.

After much tidying of my site an updating of plug-ins, I have resolved this.
Thank you for your help.
