Crash when pressing the share/unshare screen button in voice channel

I am using an underpowered Windows labtop (i5 6200U+16GB RAM + SSD). Discord would stop responding once I press the share/unshare screen button in voice channel. Yet Windows doesn't show 'not responding' message. When crashed this way, my camera in the voice channel updates every a few seconds, yet people in the chat room can no longer hear me.

I am using Battery Life focus for OpenAsar.
