First test:
1. Uninstall OBS.Live
2. Uninstall OBS Studio
3. Install OBS Studio
See if it still crashes.
If it no longer crashes, contact StreamElements, as their modified OBS Browser source is likely causing the crash.
If it does still crash, please follow these instructions:
1. Press Win+R to open the Run dialog
2. Type in: %APPDATA%\obs-studio\crashes and press Enter
3. Upload the desired crash log, usually the latest, directly to this Discord channel by dragging and dropping the file into the chat window
