I have a custom board using a 4809.  Programming is on MS visual Studio, with VisualMicro IDE 
The programming and functions have been perfect until last Saturday April 29 2023.   
The project uses all the 4 ports, but now it refuses to recognize Serial3.
If I use the '3209 chip model it compiles perfectly.
I have replaced the Microsoft VS, and the Visual studio, same result.
However, if I use the Arduino IDE, the project compiles.

I'm at a loss to explain the change in operation.

meta_gdbstub.comment=To use this debugger, install 'avr-debugger' library, add 1) '#include <avr8-stub.h>'  2) add 'debug_init();' to the 'setup()', and add 'breakpoint();' to the top of 'loop()'. Set vMicro > Debugger > 'Compiler Optimization' to 'No Project', 'No Project + Libraries' or 'None' when debugging (NOTE: This might cause compilation errors with certain code such as HardwareSerial.)

Usage: Optionally add a customer debugger to the project. A 'debugger_launch.json' file shares the same command syntax that is used by the VsCode debugger. Custom debuggers can be targeted at a board and/or variant and/or configuration name. IE: [variant].[configuration_name][.]debugger_launch.json

I contacted MCUDude, and they sent a reply that explains the problem: 
Reply says:
"Core Include Paths
Include Path res/coreX-corefiles"
Include Path riants/40pin-standard"
You're building for the 40pin-standard variant, but the 40-pin chip doesn't have a fourth serial port, only Serial0, Serial1, and Serial2. Try building for the the 48-pin standard pinout instead."

There is no way to select the package, I am using the 48 pin package.
Microchip datasheet "DS40002173C.pdf" shows the package variants.
