Error: Fail to flush static buffer

Hello TheHellHunter, I noticed that you help players with technical issues with the game, so if possible I would like you to help me with this particular problem which I haven't been able to find any answers on this forum.

Whenever I start the game with my character, when the loading screen appears and starts loading, I get this error every time and the game shuts down:

"Error: Fail to flush static buffer"

Then I have press OK or close the window and the game closes nonetheless.

If you have anyway of helping in how to solve this I would really appreciate!

Thanks
