Thank you for the post.
I am concerned about potential issues in Xcode 26.6 that may prevent crash files from being displayed, as well as Xcode 27 betas. It appears that this is an issue affecting many users at this time in this thread.
You mentioned clearing the /Library/Developer/Xcode/Products folder, but Xcode actually caches crash logs in a different directory. Close Xcode. Where is it showing here? ~/Library/Developer/Xcode/Crashes
In any case I would recommend you to file a bug so that team can take a look at the issue. Make sure you add the Xcode version and sysdiagnose file.
Once you open the bug report, please post the FB number here for my reference.
