Xcode 12 Beta Simulator Runtime not available

I installed Xcode 12 beta 2 and tried to run our xamarin project through Jenkins on Mac OS Catalina. It fails with the below error. When i build the same project from Mac Visual studio, it succeeded without any error.

SplashViewController.storyboard : error : iOS 14.0 (14.0 - 18A5319g) - com.apple.CoreSimulator.SimRuntime.iOS-14-0 (unavailable, failed to open liblaunchsim.dylib) ==> not available: Error Domain=com.apple.CoreSimulator.SimError Code=401 "The iOS 14.0 simulator runtime is not available." UserInfo={NSLocalizedDescription=The iOS 14.0 simulator runtime is not available., NSUnderlyingError=0x7fef8847b520 {Error Domain=NSPOSIXErrorDomain Code=53 "Software caused connection abort" UserInfo={NSLocalizedFailureReason=XPC error talking to SimLaunchHostService: <error: 0x7fff97d649a0> { count = 1, transaction: 0, voucher = 0x0,_

I also did 'xcrun simctl list' to view the available runtime simulators for Xcode 12 beta.
it shows the below list but fails while building.

== Runtimes ==

iOS 14.0 (14.0 - 18A5319g) -

tvOS 14.0 (14.0 - 18J5331g) -

Can anyone help me to resolve this.

Thanks in advance.
