Cannot access SmartThings app or IDE to remove device

I am getting the following error in IDE when I click on a new device that I tried to add:

Oh No! Something Went Wrong!
Error
500: Internal Server Error
URI
/device/show/227dc0eb-405a-46a2-a510-6fe6ce55ef2e

Now I can’t use my mobile app to remove the device because the app has issues logging in. Any way I can remove this device from my device list?

Thanks in advance!
