Excel scripts not working on browser

The automation tab is broken for our Microsoft account on the web version of excel. It works fine on the desktop app, but on browser, the scripts we have saved do not load, and when trying to create a new script it has the following error:

"An unexpected error occurred. Close the task pane to try again.

To use Office Scripts, you must change your browser settings to allow third-party cookies. If that doesn't work, your organization's admin may have disabled this feature.

Why can't I access Office Scripts or the Automate tab"

I've tried across 3 web browsers (edge, chrome and firefox) and 2 operating systems (ubuntu and windows 11), all of which with third party cookies enabled.

We dont have access to the Microsoft 365 admin center because we are a family account.

In our one drive, the scripts are still there.

We have previously been finding the scripts extremely useful, it's weird that they have randomly stopped working on the browser version of excel.
