Trying to launch a session and getting a error failed to download assets, any advice? could this be a issue with the servers?

Check your Windows Defender. It may be blocking access. This is what I found and it worked!

Good idea There is an article about that in the past and how to add an Exception in Windows Defender  
[urc.exe and urc.dll get flagged as Malware from Microsoft Defender](https://forums.unrealengine.com/t/urc-exe-and-urc-dll-get-flagged-as-malware-from-microsoft-defender/1802519/2)

Remember to [Verify UEFN](https://forums.unrealengine.com/t/urc-exe-and-urc-dll-get-flagged-as-malware-from-microsoft-defender/1802519/5) your installation afterwards other Anti-Virus products will have other ways to add exceptions
