Can you clear the local storage and session storage?
When you logged in, the token response is stored in the local storage. When you create a new solution, you should clear the browser storage.
If this suggestion will not solve the problem, please share

The problem is not related about local storage. Source of the problem is about IIS Express localhost Certificate
Run this command under folder C:\Program Files\IIS Express; IisExpressAdminCmd .exe setupSslUrl -url:"https://localhost:44385" -UseSelfSigned to add a new certificate for the specified url.
If anyone encounters the problem, just change the url in the command for your needs.
