Xcode 12.1 crash when try to open manage schemes...

I am using xcworkspace, and every projects that I have the same issue while trying to open manage schemes

You can find the crash report from text attachment below


I just realized that it only happened when I am using second monitor
I'm experiencing the same issue with Xcode 12.1 and all newer versions.
It happens ONLY on my second monitor (configured as my main monitor).
It does NOT occur when I open Xcode on the integrated monitor of my MacBook Pro.

The crash occurs in the "Behaviors" menu and when trying to "Manage Schemes".

I attached a crash log for one of the cases.

My fix for now is to move Xcode over to the integrated monitor before opening one of the menus.



I have exactly the same issue ! And if, once manage shemes opened in MacBook Pro monitor, I switch it to extern monitor, the crash happens !
I have the exact same thing and only on an external monitor. Thanks for the workaround! Hope it gets fixed soon.
exactly, only happening when using extra monitor
Yup, I opened the manage scheme on second monitor and it crashed. Works fine in primary monitor
I experienced this exact same issue, just needed to move(drag) xcode to laptop monitor.. external monitor causes crash
Facing exactly the same problem: XCode crashes on some actions only when I use an extra monitor. The same things are working ok if I use laptop only. 🤬🤬🤬
