Error when building game: 'IOException: Sharing violation on path'

Hey everyone!

I have a major issue with my 2d platformer game. It's completely finished now and has worked absolutely fine both in-editor and when building until now. When I press Ctrl + B to build it, the loading bar reaches the end and gives me these errors:

'IOException: Sharing violation on path Temp\StagingArea\Pippy The Bird.exe" or "C:\Users\Adam\Desktop\Unity Game Build\Pippy The Bird.exe

And:

'Error building Player: IOException: Sharing violation on path Temp\StagingArea\Pippy The Bird.exe" or "C:\Users\Adam\Desktop\Unity Game Build\Pippy The Bird.exe'

I've even tried building to a folder on two different PCs, and it builds fine with no errors... Until I go to play the exported game and my mouse curser just spins endlessly and it never loads. If I restart windows explorer in task manager it's like I never tried to run the game in the first palce.

Please can someone help me here! I've literally finished my game for a project now, and the only thing stopping me from being able to hand in is building the thing as a .exe. :/

 

i would guess that the game is still open, when the editor tries to overwrite it, while copying it to the target path. Maybe it didn't close properly.

 

I've figured out from restoring from an earlier backup: If I build the game without a custom logo it works fine, however the moment I apply a new picture/texture for the .exe's launcher icon in the Unity Build Settings tab it causes all of these issues. It's completely bizarre, but is something I would like to amend!!
