I am getting an intermittent crash when I try to log into my Unreal Engine 5 game. So sometimes the crash happens, and sometimes everything works completely fine. The crash seems to happen right before I travel to the main map (right before gameplay). The map was originally setup as a partitioned map, but I disabled the partition as I didn’t want that feature anymore. I am thinking that perhaps the problem is how GameLift is handling the partition and sometimes doesn’t travel to the map correctly? Maybe I need to disable some partition feature, but not sure…Here is some information on the setup:
- Unreal Engine version: 5.0.3
- GameLift SDK version: 3.4.1
- EC2 instance: c4.2xlarge
- Number of simultaneous processes: 3 (takes up about 35% CPU and 35% RAM)
Below are the logs showing the error. Your help would be much appreciated for this!
