Search for PNGs with similar file names in the game folder and change them to the same name as the wrong load.
Sorry, I'm not a native English speaker.
This error may point to a wrong name or an incorrect identification of "spacebar" under different systems. I don't know how to explain it, it's usually caused by "the target file required by the program cannot be obtained".
In addition to changing the name, try to copy and paste the file to make multiple files with directional names to ensure that the program code can obtain the file with the same name as the required file. If it is impossible to obtain, you can try to create a blank 480X480 PNG file and place it in the file Renaming in the folder, this will cause the avatar to be white framed or transparent, but it will not affect the game progress.
