First of all, make sure your drivers are up to date. Check if the important ports of the internet are open, that is the main problem in most of the cases (You have to check that depending your Internet provider and model of your modem), but I think you will have to call your Internet Provider to know this, there are ways to check them but I don't remember how, you could search for them.
-Try downloading the game again (Including the last "Localize" folder).
-ALWAYS open "DBOG Launcher" as Admin.
-If your internet is slow, try disconnecting everyone in your house (if there's more people) and check if still crashes.
-You could run your antivirus (It might not fix anything, but just in case).
-Deactivate your firewall and your antivirus, they could be interrupting your connection to the server.
-Do you have another PC? Try the game there, if it crashes, at least you know it might be your internet.
For now those are the things I have in mind that MIGHT fix your problem, if I think of more solutions, I will let you know!
Hope it helps!
