Sorry to post another one of these but I have tried everything so I will try and give as much info here as possible.
Windows 10 (Have all three of the following running in compatibility mode for windows 8: SB.exe - SBLauncher.exe - xm.exe and all 3 running as administrator)
Malwarebytes (Currently not running/turned off)
Windows defender, added SB.exe - SBLauncher.exe - xingcode.dll - xm.exe to exclusions separately along with the directory so no issue there I would assume
I have installed all of the files the install me file with all Microsoft Visual C++ 2005 to 2015 and directx9
Flushed DNS
Tries with firewall turned off and also added the three following files to the allow list in the firewall: SB.exe - SBLauncher.exe - xm.exe
This is a completely fresh install of the game showing up as 10.5GB
I do have a VPN but it is not running
There is no run_game.bat which is mentioned in the sticky so I run the launcher, hit play, log in successfully and hit start game - nothing happens, no window in the bottom right, nothing in the taskbar drop-down background tasks thing, nothing in the task manager... no signs of life at all. If I run SB.exe I do get the XIGNCODE3 window in the bottom right and I see scarlet blade in the task manager but nothing else (as I guess is expected).
I'm at a loss, any help would be great.
Edit: I tried with the VPN turned on and now this error pops up: gameguard error e0190304
Edit2: I have tried the XIGNCode fix - Now I get a poppup with 0xE0191009 - Error: Failed to update XIGNCODE due to insufficient hard drive space or because the program is being blocked by a firewall or anti-virus software. (Definitely not a lack of hard drive space). I added the prgrams back into the firewall allow list, with the VPN active the list is different and now I get no errors but I'm back to square one, when I launch the game, nothing happens.
Edit 3: I have Disable Full screen optimisations on both SB.exe and SBLauncher.exe - no difference
