I noticed that a lot of windows exports have the pck along with the debug console active. If you are like me and want to remove them, here is how:

When exporting the project, go to the Windows export, then   Options >> Binary Format >> Embed Pck   and set that to true.

When pressing the button Export Project and when you are choosing the destination for your game, the debug check_box will be at the bottom left of the screen.

Also for Macos, if your game doesn't run and you get something about the "." thing and a pck error, it's probably because you have a period in the title of your game.

Of course, all of this is for future reference. Good Luck!

Also, people with errors like "." or pck is missing for windows should include the pck or embed it into their game. And if your like me with an evil avast antivirus system that stops almost all games without a known publisher, set the company name to your itch.io profile name or something
