New error message in PowerApps

I have had a PowerApp in operation for over a year and it works fine. But now I suddenly have an error message with a datacard that I don't understand.

In a datacard, the app is supposed to check wether the email address entered (by people picker) corresponds to the email address of the current user. I have therefir used the following formula in the error message of the datacard:

Now this formula is shown to me as incorrect. The reason: "Regular expressions must be constand values".

Can anyone help me?

Many thanks for the support!

The IsMatch() function is meant to be used with a Regular Expression; it does not determine equivalence between two strings. Try this instead:

Coalesce( Parent.Error; If( !IsBlank(DataCardValue5_1.Selected) && Lower(Trim(DataCardValue5_1.Selected.Email)) = Lower(Trim(User().Email)) ; // Warning message here ) )

Hope that helps,

Bryan
