Vue 3, Vue Router 4, web hash history router

I have a url with a query param that gets inserted, but Vue seems to ignore it and it’s causing weird redirect issue for my application.

For example:

Is: Https://example.com/?foo=bar#/

Should be: Https://example.com/#/?foo=bar

I don’t know why the #/ is getting stuck on the end and Vue must be looking after that to find any query params, so that seems to be why it’s not being found. Any ideas?
