Error can't open UE5 because of this error

Hello Everyone,

I’m having some major issue not being able to open my UE5 because of this error message. Just wondering if anyone else had this same problem?

So I’m having a similar issue, and I’m not a UE5 developer at all. I just happened to find this page that you posted 2 hours ago, as it seems we’re the first ones to start reporting this issue.

It happens whenever I try to “brew {update,uninstall,install}”, and even when I simply run clang -v, lol. It keeps telling me to update my Xcode Developer Tools, and when I do, the issue persists, and it tells me to update again. All of four my Macs are abruptly doing this. I’m suspicious that Apple may have screwed something up with the latest macOS 15.6 and/or Xcode developer tools they’ve pushed out.

Edit: Just before hitting “send” on this reply, I noticed that buried within both of our error messages is:

Please ensure Xcode packages are up-to-date — try running xcodebuild -runFirstLaunch

Open Terminal and do that. It fixed my problem. :slight_smile: :+1:

Cheers!




I’ll leave my stack trace and error message below, in case it should help more web searchers find this solution:

Hi thanks for that. I seemed to managed to get it to work by doing that. Really appreciate it.

Incredible that I found this post right when I stumbled on this problem. Had the same issue where all my IDEs, CLI and git client were broken or complaining. Can confirm that this works. Had to login just to show my appreciation. Cheers!
