Error reading HeaderError loading sprite from file bug

I tried to save a file that i had been working on for a long time and saving often but when i saved it this time it came up with an error message saying “Error writing compressed pixels”. I shut down Aseprite to see if that would fix it and i was ok with losing a small amount of work, but when i then tried to open it it came up with this new error message.

is there anything i can do to fix this? I really dont want to lose this work.

@ChickenWithRice contact me to with your tilesheet.aseprite file and we’ll see if we can recover it.

Sorry @ChickenWithRice, I’ve received your file, but unluckily the file doesn’t contain any information, it’s related to this problem:

(I didn’t receive one of these report in a long time, so I’m not sure if it’s something Microsoft has solved recently, or we’ve solved in recent versions of Aseprite.)
