Error tells me part of arduinos own code is wrong

Error below says that there is a missing semicolon in arduinos own code, and it has never thrown this error before.

Which Arduino board have you got selected in the IDE ?

3

You forgot the ; at the end of this line

4

The UNO R4 WiFi

5

Thanks, I don't get why it threw that error but thats what was wrong.

7

C++ requires a semi colon at the end of that statement.... so that's what the compiler tells you but it gets the line of code wrong because of apparently a macro

what type of Arduino are you using for Serial to be a macro ?..

8

The next line in your code is

, aka the UART. It's telling you the error is just before this line, which is how I found it.
