Reloaded a backup edition of my site and this now seems to be working. Seems to be down to an extension that I installed via composer which was not agreeing with the magento system.
After some additional research this issue could be caused by the repositories in the composer.json file. Removing all but the primary repository seems to fix the issue.
An example is given below.
Before:
"repositories": { "0": { "type": "composer", "url": "https://repo.magento.com/" }, "data-migration-tool": { "type": "git", "url": "https://github.com/magento/data-migration-tool" } }
After:
"repositories": [ { "type": "composer", "url": "https://repo.magento.com/" } ]
It may help you to resolve issue.

Can I keep this?
"version": "2.3.5-p1",
"minimum-stability": "stable",
"repositories": [
{
"type": "composer",
"url": "https://repo.magento.com/"
}
],
"extra": {
"magento-force": "override"
}
