Borderland Pre Sequel - Stopped Working

I tried to play Borderlands Pre Sequel on Steam, but after I start a “New Gme”, the game stopped working and crashes.
I’m using Windows 10.
Can someone help me please?

Have you done the usual Steam trouble shooting steps (relaunching client, verifying game files, etc.)?

Yes!

All I can think of immediately is if the save games folder got locked so the game can’t create a new character. Maybe check permissions - even if it was set correctly before updates to AV software sometimes result in rule changes that can result in such things.

Otherwise, you can file a support ticket with GBX/2K for further assistance.

I tried to do what you told me, but it didn´t work.
Where can I open a support ticket?
