Issue with VLC casting to Chromecast on Android

I consistently have issues casting from my Samsung (S23+) phone to Chromecast. Every 5-10 minutes it loses connection/can't find the file. Whether it's a local file on my phone or a file from my local network. Simply opening VLC up seems to resolve this. There has to be some solution aside from leaving my phone open/unlocked with VLC open while streaming.

I can cast other things from phone to Chromecast without issue: whole phone (via google home), YouTube, amazon prime video, etc. VLC is the only one that has any issue. This was an issue on my prior phone (Samsung galaxy S7) as well. Restarted router and Chromecast many times but the issue persists.

Hoping anyone might have ideas for how this can be resolved, as VLC is definitely my preferred player in general, but I want to cast to my TV more often than not.
