After installing BetterDiscord, Discord crashes on launch

1. Press Win + R and type %APPDATA%/betterdiscord

2. Look for these files in the plugins folder and delete them:

0PluginLibrary.plugin 
0PluginLibrary.plugin.json
0PluginLibrary.config.json
0PluginLibrary.data.json
0PluginLibrary.raw
ZeresPluginLibrary.plugin
ZeresPluginLibrary.json
ZeresPluginLibrary.config.json
ZeresPluginLibrary.raw
ZeresPluginLibrary.data.json

You might not have all these files, so just delete the ones you have.

3. Restart Discord again via the system tray.

4. Download the plugin. Open the hyperlink, and Press Ctrl + S to download it.

5. Copy and paste the downloaded file to your plugins folder, then restart Discord again via the system tray.

That's all. Discord should no longer crash on launch!
