Here are the steps of when it happened.
1. I saved a symbol art into a different slot.
2. Deleted the other symbol art.
Location: I'm at one of the mining bases you defend for a trigger. Waiting in the lobby area just outside the gateway ship. I still have my game open and it's still not responding, sound can still be heard though. Not sure if it's active sound or repeating since no one was around me.
8:25pm EST 8/29/2020 is when this approximately occurred.
I've never had issues with this game like this so it might be some error when deleting a symbol art or it could be something else, I don't know. I will just have to force close my game.
This is the log from SymbolChat log file.

and this is the end of the Action log before I went into the gateway ship.

Showing I took out the trigger from storage, bought those items and that's all it shows.
