fatal error: avr/io.h: No such file or directory (on Windows 11)

Question

So I'm using arduino 1.8.18 installed on zip file. I am using the HardWire library. The project is the STM32 quadcopter by joop brokking. http://www.brokking.net/ymfc-32_downloads.html

complete error -

As you can see I'm using the stm32 lib by roger clark. The ide is unable to detect any of the avr/.h files. I tried replacing the path in twi.c, but then the other avr files start giving errors.

Why is this happening?

• KIIV: For this arduino ide you can add portable directory (arduino-1.8.18\portable) and add only cores/libraries you want to use for STM32. Or just delete all colliding libraries
