trying to load from uno boaed to library windows 11
You are going to need to supply more information than that.
Can you draw a diagram?
What Windows 11 library?
What is the connection between the UNO and Windows?
Are you trying to upload a sketch using the IDE to an Arduino? https://support.arduino.cc/hc/en-us/articles/4733418441116-Upload-a-sketch-in-Arduino-IDE
Are you trying to install a library using the IDE? https://docs.arduino.cc/software/ide-v1/tutorials/installing-libraries/
Welcome!
It sounds like you would like to take code from your Arduino UNO and use it in a Windows 11 library. I am also assuming you are hoping to recover the original source code that was in the IDE when it was compiled.
Unfortunately, the code stored in the UNO is not saved in human-readable form. Once compiled and uploaded, it is converted into binary machine code that the processor understands. The original sketch (.ino file), comments, and variable names are not stored on the board.
If you still have the original project files on your computer, that is the best place to start. If not, it is technically possible to read the binary back from the UNO using tools like avrdude, but converting that binary back into readable source code is extremely difficult and will not reproduce your original sketch.
If you can describe what you are trying to accomplish, there may be a better path forward.
