"ID Cannot Be Found"

Personal Log: August 2nd 2017
I finished school a few days ago and went on Roblox to get some time to pass by. I joined my friend who was playing Natural Disaster Survival at the time. We talked about a few things at school and what we're going to do tomorrow.

I played with him for an hour until I left for dinner, and I went on Roblox again after. I saw my friend was offline so I would grind in some tycoons just for fun. When I checked the time, it was already past 8 o' clock at night, it was verh dark outside so I left the game, turned off the tab and shut down my computer. I would go to bed and call it a day.

I woke up at half past 7 and went on my computer to play some Roblox. My friend was online, but not in a game, so I chat to him what we could play. He suggested we tried a new game, but I disagreed because the players who played the game longer would take advantage of us.

I suggested we would play Natural Disaster Survival again, but he wouldn't go with it, we finally agreed to play some Work at a Pizza Place. We played for a few couple of hours until my friend had to go eat breakfast, and he wouldn't come back after. I asked why, and he responded simply "he wasn't feeling like to". I didn't say anything, so I continued playing.

A few minutes later, my game would crash and a message would appear following the crash after 5 seconds. It read as "System could not detect an ID, try again later." I didn't know what it meant, so I would search it up on the wiki, but I couldn't find anything that mentioned it, I thought it was very rare and I might be the first person who can document it. Which, I would do so.

I would wait all day for a response, but no one replied to my message. Soon, I would go to bed, hoping someone could help me with this.
