Error during load after selecting character. (file problem)

Just as the title says, after creating my first character y click the play button, and during the loading screen this message pops up:

So after clicking on "OK" or trying to close it, it continues to appear. After many tries, another message appears saying that the game must be closed and asks for permission to send a crash report.

I came to the forum, and found about the Pack Check, used it and it didn't find any problem. So I reinstalled the game, by first deleting the "content.ggpk" file, but the message appears again.

Does anyone here know how to solve this?
If you need image of the PackCheck or the "game must close" message and crash report just tell me and I will upload.

Does no one have any idea about what could be wrong?
By the way, I erased all the data from the game, downloaded the client again, patched the game, and still have the same problem.
