Error code: (Container.js:227)

HI ya'll

I created a character in 2017 and now when I open it I get the following Error: "Error code: (Container.js:227)"

I'm on Windows 10 ChA 2.1 now.

I based my Charater off Evans. It used to work fine but haven't used it in about 3 Updates or more and now it's not working.

Any Suggestions/ Solutions would be greatly appreciated.

Thanks In Adavance
