Question: Problem entering a math equation in a text region.

Today, I trried to enter an equation into a text region using Ctrl+R (In Maple Flow 2023.1), like I have always done in previous releases of Maple Flow. Well, today it did not work. I tried to enter the equation Q=W+mCv(T2-T1). When I tried to enter the equal sign after the Q, the program would not allow me to do it. I would press the equal sign and nothing happened. I tried :=, but it would only enter the :, it would not let me enter the =. Any help will be appreciated.
