Every time I open UE5, it will crash directly. After uninstalling the engine and re downloading, UE5 will still crash. UE4 can be opened normally. I don’t understand why?This is the report：

Hello,
After some research & test, here is my fix :
1/
In C:\Users\yourname\AppData\Local\UnrealEngine\5.1\Config
Add :
[/Script/UdpMessaging.UdpMessagingSettings]
EnabledByDefault=False
EnableTransport=True
bAutoRepair=True
MaxSendRate=1.000000
AutoRepairAttemptLimit=10
WorkQueueSize=1024
bStopServiceWhenAppDeactivates=True
UnicastEndpoint=0.0.0.0:0
MulticastEndpoint=230.0.0.1:50000
MessageFormat=CborPlatformEndianness
MulticastTimeToLive=1
EnableTunnel=False
TunnelUnicastEndp…
I hope the above is the solution you need!
Thank you for your answer. The startup engine will not crash, but it will crash when you open the project.
