the solution I set accept is working well for my project , if you check your Derived Data is set to unique and the Xcode is still crashing . may be you need to send the crash log in feedback to make apple developer pay more attention to this problem ! I have delieve a post in Feedback'app a month ago , but the problem is be rated as not happed more than 10. so a month passed , the developer seems still did not fix it

oopts . the crash happed again ,the method I metioned above is not working ..

I found that if you open the project with the .xcodeproj and let it finish the indexing and then open the project with the .xcworkspace to open the project , the crash will not happed , I use this method with Xcode 15.4 beta , maybe you can try it
