I just tried to stream today only to have my OBS freeze two times in a fifteen-minute span and had to call off my stream. Any help would be greatly appreciated.

The streamelements plugin is known to break OBS. Completely removing it use to solve the issues. Use the uninstaller they provide, then go to %appdata%\obs-studio\ and manually delete the leftover files they keep in here because this files keeps interacting with OBS causing issues. Now you need to uninstall OBS and reinstall it in order to fix any other changes this plugin have perform.
Remember to first backup the scene collection and profile.
Of course, if you do want to use the plugin, you need to contact their support.
Verify that any plugin you have installed is updated and compatible with the OBS version you're using. Remove any you don't use or that is not an issue for your stream to remove it.
