USB games are not working properly?

Why is that? That happens again and again, sometimes it happens that I can't even get into the game and have to format the USB stick again, why is that?

PS: I HAVE AN XBOX ONE S

Do you play video games via USB sticks (from your question)?

Sometimes I have a similar error message when I use original discs, but then I restart the Xbox and everything runs as usual.

You don't see anything in the picture except "The game or app is not installed" so install it.
Instead, write your question in the field where you write your question, yes?
Please a meaningful title and not "Why usb why that?"

Do you mean your HDD (hard drive). USB stick is completely different

Stick

Did you install a game on it?

Yo

There you have the problem. Buy an external hard drive or install a larger one directly.

I do not recommend USB sticks. Damaged my run in Ace Combat 7. Now have a 2TB HDD disk. Was on my One X. The reason is that sometimes the sticks are simply "removed" and suddenly the game ends. It happened to me VERY often when I had to wait for an HDD.
