Give more information about what is happening, when and how. Is it with only one user? How is this user different from the others, etc. Maybe this happens when some group chat is open with lots of history? Also provide logs from here C:\Users\User\AppData\Roaming\Spark\logs\ Logs are scattered between various files, so check them all and copy some of the newest entries here.

We saw the same thing at our company. Turned out to be a combination of Spark and newer versions of Java. If you’re using the online version (without Java) of Spark, try uninstalling it and download the full version with Java included.

I have tried to run Spark 2.8.3 with 8u162 version and it was fine (Windows 7 x64). Oracle usually releases odd and even version at the same day and auto-update usually installs odd version (161). It seems it has less feature updates and changes and mostly is about security fixes. Even versions (162) contain more updates. We usually use even versions to bundle with Openfire/Spark. Although it might be a slight chance, but one can give it a try with 162. http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html
