This is a familiar experience with IDE 2.3.6 and the inexpensive NANO boards.
The older 1.8.19 compiler works fine for me and the NANO boards; however, ...
What am I doing wrong with the 2.3.6 compiler?
This is a simple code that works with 1.8.19 but not 2.3.6. NANO board photo attached.
Your comments are welcomed.

The path should only contain basic letters, numbers, and other simple characters (
Arduino IDE periodically deletes the contents of this folder (the files stored under it are only cached there for the sake of efficiency, and it can always regenerate the files on demand), so you should not use this folder to store any valuable files.
