I was facing same issue. There is no clear information provided by Apple.
But, If you have added iOS 14 widget and facing this issue then update the target membership of your fonts with the Widget Extension will do the trick.

I have also faced same issue while downloading the dSYM. I have found my dSYM under TestFlight build section. Check my post here - https://stackoverflow.com/questions/65210768/from-where-i-need-to-download-the-dsym-from-app-store-connect

Noticed this same problem in Xcode 12.4 also.
A workaround that works for me:
Click on the custom color to bring up the color chooser.
The color chooser is the wrong color, but select any any other color in the color chooser.
Do CMD+Z to undo the color change. Magically the original custom color is now selected in the color chooser.
Hope it helps!
@Jason Yes. You are right. We ware doing this previously :)
