IntellJ | Exception in plugIn GitHub Copilot (1.1.20.1417)

Question

After updating my copilot plugin in IntelliJ I tried to log in where I am redirected to a webpage, I enter my information, click authorize and the page congratulates me with being all set. However, when I return to the IDE I am shown a pop up with the following error message:

"The login to GitHub failed. Please try again"

In the bottom right of the application window I get an indicator of IDE internal error (IDE fatal error):

Things I have tried with no results:

• removing the copilot plugin from IntelliJ, downloading an earlier version of the plugin, and importing it from disk to IntelliJ but I still get the same issue
• updating IntelliJ
