Game will not launch after DLC is added

[LS54]

I'm actually not sure if it's because of the DLC or not, but I haven't played Cyberpunk in about a year or so, since getting the DLC the game point blank refuses to launch. I'm getting that "woah Cyberpunk 2077 has flatlined" message, I've looked at all the tips online for how to fix this, and I have done the following:

Updated my Geforce graphics card drivers
Updated regular display drivers
Turned off all unnecessary background programs
Verified the integrity of the game files
I don't use mods, never have
Disabled steam overlay
Running the game as administrator
Reinstalled/repaired C++ redistributables
I have run SFC & Dism
Reinstalled the game

None of these have worked, it's beyond frustrating, has anyone else had this problem?

Thanks

have you reinstalled the game after you got the dlc?

I know you probably did but have you disabled cloud saves/cross saves and done a complete clean install without keeping any old saves?

Completely clear your PC of all Cyberpunk folders across all directories and disregard any previous saves. Then disable cloud and cross saves.

Also, try adding the launcher skip to the games properties, perhaps it's just the launcher crashing?

Check your firewall to make sure it's not somehow interfering.

Also, I'm assuming by "point blank refuses to launch" you mean that when you click to open the executable via your desktop or launch the game via Steam's Library page that it immediately crashes without anything else happening?

Or

Do you actually get into the game? Does it crash after pressing space or while loading? Etc.

EDIT: Also a dumb question, but you are using the 2.0 builds right?

To answer all questions:

ZYED
-Yes I've both reinstalled it with and without the DLC

Chaosolous
-I haven't tried a completely clean install yet, I have now deleted the save files on my pc, and disabled cloud saves. I'm reinstalling now, but will take a good couple of hours to download again.

-I have confirmed that it isn't the launcher that is the problem, I bypassed it and get the same result.

-I have checked my firewall, and the game is definitely allowed through.

-Yes the game does immediately crash without anything else happening

Thanks for the tips, I'm hoping that it is the save game issue, it seems like a lot of people are getting some issue with the DLC and previous saves. Will check back in later.

EDIT

Solved - It turns out that despite being allowed through the firewall, it was giving Ariva antivirus a false positive. For anyone else with this problem, just turn off real time protection.
