i would assume thats due to the fact that clipnote has a bunch of web and file related calls, and windows antivirus software just really hates anything that isnt well known because its paranoid af, from an antiviruses perspective it has no idea what the code is ACTUALLY doing, it just knows it COULD do harm. as long as you downloaded from itch.io it should be safe. logically, the most recent clipnote file has been up since 2019 and no ones had an issue, if my software was doing anything actually malicious my itch account would probably just be gone ngl.
