Hey overreal-
Does the crash occur in a new, empty project with the same settings? If so, can you provide the callstack and logs from the crash for additional information?
My crash log. When I play with 3 players, editor uses “Play As Client”, the crash occurs only when editor tries to host game.
Edit: My project is a blank project. All settings are shown in this post. First issue was that client was unable to join. Second is as overreal mentioned, editor will crash with the settings. Crash log for second issue.
Hey WeiLiang-
Creating a new project and following the settings in the provided link did not cause a crash when hosting/joining a game. If you are still getting a crash, can you provide a new, minimal project that reproduces the issues?
Hi ,
Below is a link to an empty project with two map. The first map will display the widget as show in the link I provided previously and the second level is just to show that there is a change in map.
New empty project
For crash : editor must use “Play As Client” and Host Game must be pressed.Crash Log
Other issue : When editor uses “Play As Lister Server” and additional processes try to join via “Join Game” button, I get the following log. Previously in 4.15.1 I was able to join using this method.
Hi , yes it occurs in a new project. Here it is

Repro:
Using the packaged .exe, I can host and join but a new issue surfaced (added below). The current issues are,
OT: This issue shouldn’t be here, but i’ll just add on anyway. Packaged .exe ignores window size set, be it the size under “Play in New Window”, “Play in Standalone Game” or “Multiplayer Options”
I realized the settings are missing because I cleaned the temp folder. So you will need to
So this is another issue, same project. I change it to “Play as Listen Server”, on step 3. It does not crash at step 4 but the child games, their UI will disappear
Hey guys-
Thank you for the sample projects, I was able to reproduce the crash on my end. It appears the issue is using the “open LevelName” console command with the settings you mentioned (Use Single Process unchecked / Play As Client). This has been reported as Unreal Engine Issues and Bug Tracker (UE-46261) . You can track the report’s status as the issue is reviewed by our development staff. Please be aware that this issue may not be prioritized or fixed soon.
