I’m glad LeGone was able to provide a workaround below, however I would like to investigate the crash you’re getting. To help me begin, can you provide some additional information including the full callstack from the crash as well as the log file? Assuming the solution of setting bEnabled=false is what you’re using, this would mean setting it back to true and letting the crash occur. You can then copy/paste the callstack after the crash. To get the logs you need to go into the project’s Saved/Logs folder and find the most recent after the crash.
Additionally, can you provide information on the project itself? Which template was used as the base of the project? What engine version was the project originally created for? What version were you coming from prior to switching to 4.11? Are you using the binary engine from the Launcher or an engine built from GitHub source code?
The game is third person online shooter based on “third person” template with insertions from “first person shooter”. Started on 4.7.3, last prior version is 4.10.4. Engine built from GitHub.
Give me a couple of days for logs and full callstack, I’ve reverted all changes to 4.10.4
UPD: logs and crashdump from binary engine: link text (On binary engine it crashes too)
The issue of the IpGuid being null should be fixed in 4.11.2. If you update your engine, you should be able to set bEnabled=true in the Voice section of the DefaultEngine.ini file without a crash. If you’re still having the crash occur let us know and we can investigate further.
