How do I get support for Xcode? I have asked a question about the simulator not working properly but no-one has been able to help here. How do I get assistance?

I have recently had to reinstall Xcode as it was stuck when trying to update it. Since doing this I have been having significant trouble getting builds to run on my iOS simulators. If I build my app in Xcode the simulator application no longer opens and when I open it manually the simulator will not receive and run the build. Sometimes changing the simulator can help me run the build however this doesn't always work and is inconvenient as a workaround. Any advice on getting my simulator to function properly again? Xcode doesn't appear to be sending builds as it should or simulator is not receiving them properly.

Can someone tell me how to do complete reinstallation without factory resetting my Mac? The simulator does not work at all anymore and no-one has given me any advice on my other questions and it has been a number of weeks now so I give up on getting this resolved normally and would like good advice on properly reinstalling Xcode.

Simulator doesn't open when running builds on xCode sometimes restarting helps but this is happening more often than not now. Any help would be appreciated!

When building the app the simulator does not launch as it previously did, using the latest version on an intel MacBook Pro 2020. I have factory reset the Mac several times and reinstalled Xcode numbers times and have reverted back to previous version which has not worked. Not had any assistance from this community previously can anyone assist me with this now?
