One day I opened Unity I tried to access my control scheme to edit something via the New Input System I'd implemented a while back, and the logo showed up as: (Possibly corrupted .inputactions file on the right: 'PlayerCon...'. Unity still recognises this as a .inputactions file but seemingly can't read it? I tried creating a new control scheme - 'NewCont...' to the left - after this issue and that works fine.) When I try to open the file to edit my control scheme, windows asks how I want to open the file (trying to open with Unity or other programs doesn't work), and I have have these errors in the Console: Plus, the inspector no longer gives me options: Clicking 'Edit asset' just adds to the Console error count in the image above, and 'Open' makes windows ask what program I want to use to open it, as mentioned above. My project still works in editor mode and the control scheme still seems to be operational, and the generated C# script seems intact and functional. I just have no access to edit the control scheme. Using version control via Dropbox Rewind, I went back to a prior build and the file is still corrupted so I'm not sure what the issue is. I don't want to continue coding in case any subsequent changes affect this issue in some way, and I may potentially lose more progress. Has anyone else experienced this issue? Is there any fix to access the file again? FIX: Clicking the settings button in the Inspector, then clicking 'Reset' opens the file up: View attachment 836245 Then I tested a few things and noticed that the issue is: some of my 'Actions' names had special characters in them. When I changed their name to use just letters and generated another C# class it worked! Note: the settings button in the Inspector wasn't clickable for me when the problem first arose. So if you also encounter this issue, restart Unity until you can click it.
