I ended up on this thread while googling an error with a similar message and log. In my case, I got the error while working on building a library with CocoaPods and the fix was to add XCTest to the list of linked frameworks. # CombineTestHelpers.podspec Pod::Spec.new do |s| # ... s.framework = 'XCTest' # ... end You can find the full .podspec here. I'm not sure how relevant this is for this particular issue, but hopefully it can provide some inspiration. 🤞

I run into this today, too. 3 out of 7 of my screenshots failed. Consistently and always the same three. I tried renaming the file and exporting it as a PNG without the alpha channel, but it didn't work. What worked was going out of the "Media Manager" page re-uploading only one of the "invalid" screenshots. When I went back to the home page for the app, the screenshot didn't show the IMAGE_TOOL_FAILURE error. I repeated the process for the other two, again by uploading only one via Media Manager and then going out of that page, and it worked. Go figure...

This is still an issue in Xcode 14.1 (14B47b), at least for \u{2011} (Non-Breaking Hyphen) which gives: invalid unicode sequence: \u{201
