Cannot check webgl build

The build was working very fine.But suddenly it started to show uncaught abort(-1)

release build callstacks are useless unless you enable “debug symbols” in the player settings. what’s in the log?

Sorry, I didn’t get you

please reproduce it with a Development build, or enable Debug Symbols in the Player settings, then post the callstack again.
As far as log I meant the browser log.

If I make the build with Development, I can’t upload it to server. Internal Sever error is showing at the time of uploading.

is there any solution?

then try the other option I suggested: “enable Debug Symbols in the Player settings”
