icc Profiles error on Macbook Pro running Big Sur

This would ideally be a question for Apple's 'Colorsync users' forum.

https://lists.apple.com/mailman/listinfo/colorsync-users

However, although I've not seen that specific error before I am aware that errors flagged in the Colorsync utility are said to often be spurious. If everything works as you'd expect then it would seem safe to ignore. 

I googled the error, maybe you did too? but did not see any useful solutions.

Header message digest (MD5) is not correct

I hope this helps
