Platformio serial monitor not displaying output

[KirillMcQ]

I have a Teensy 4.1 hooked up to a Windows laptop, and when I upload some code that prints to the serial monitor, nothing is outputted.

Here is my platformio.ini:

[env:teensy41]
platform = teensy
board = teensy41
framework = arduino
lib_deps = 
	adafruit/Adafruit MPU6050@^2.2.6
	adafruit/Adafruit BMP280 Library@^2.6.8
monitor_speed = 115200

I added the monitor_speed because that is the speed my program uses. Any tips?

Have you tried your code, or even a very simple "hello world" program, with Arduino IDE 2.2.1 using Teensy installed from Boards Manager? If printing also fails with Arduino IDE, perhaps try with a different computer and/or different Teensy board. If printing works in Arduino IDE but not with PlatformIO, then you can at least confirm the Teensy and Windows drivers are working properly before trying to solve the issue with PlatformIO.
