After I changed the column names, all formulas using the Choice field seem to throwing error "Name isnt valid. This identifier isnt recognized" . Formula: ThisItem.'Choice Column'.Value A red underline appearing under Value.
Same formula works for choice columns in other list.
Did you change the name of Choice column? Can you try to delete and recreate the connection so that the powerapps point to the latest state of the data source.
Hope this Helps!

Do you change the column name of the Choice field in your SP list when editing your canvas app?
If you changed the column name of your SP list, the original column name within your app would be invalid. Please consider refresh the SP list connection or re-create a new connection to SP list from your app, then check if the issue is fixed.
