Expected Behavior for Clicking on Back Button After Login

Currently facing an issue where after a user logs in to my Angular application and then clicks on the back button, they are presented with a broken page and infinite spinner (loading indicator).

I saw this issue and am now curious as to what the expected action should be for this scenario?

Should a user even be allowed to click after landing on the home page after logging in? Should we re-direct them back to the main page if we see that they are already logged in?

Thanks
