Blyka's Door - Troubleshooting

Game can't save / Gamepad freezes the game on title screen until unplugged.
Happens when antivirus software doesn't allow the game permission to create save files. Make sure the game has full permissions and isn't sandboxed or anything.
Game immediately freezes for an extended time but may eventually work without music.
You're likely on Windows 10/11 and trying to run Mega Man Endless, SD Powered Up, SuperDanny 2, Green Biker Dude, or the Tuttle demo. These games use music plugins that Microsoft broke.
My intention is to eventually update them, but in the meantime, they apparently still work on Linux, and occasional success happens on Windows when you right click the .exe, Properties, Compatibility, "Run this program in compatibility mode for: Windows 7 (or Windows 8)", Apply, and run again.
"Failed to load game data. File seems corrupted." or "Error: Cannot read the game file."
It seems Game Maker games have trouble with certain printer drivers (?!) and disabling said drivers might fix the issue. See this topic.
I've also solved "Error: Cannot read the game file" on Windows 11 with right click and "Run as administrator."
Music disappears from all or certain stages while playing, but the game runs fine otherwise.
Closing and opening the game should fix it. Usually means the music DLLs crashed, which shouldn't typically happen. Might be more likely when audio sources change, e.g. connecting or disconnecting a laptop with a TV or some such while the game is running.
Game crashes almost immediately with audio trouble on Windows 8 or later.
This happened to me with some of my older games, and I found a solution by way of this topic.
Game starts but doesn't play any/some music or sounds--may eventually crash.
Only seen this on Windows 8.1 for certain, and it seems to be a case of PC derp; a computer restart should fix it.
Something not covered here.
-Make sure none of the game's external files have been moved or anything.
-Try a fresh unzipping of the game.
-Computer restart can work wonders.
-Searching "game maker [issue]" can turn up great results.

If none of the above solve your problem, feel free to get in touch with me here and I'll see if I have an answer for you. No promises though!
