Portal 2 Crashes on Launch

[Kefty]

SOLVED When I load up Portal 2 and any mods associated with it my game will attempt to load for 2 seconds then stop, it doesn't even pull up the game. I've tried every fix I can find on the forums and on YouTube and not one thing seems to work. Does anyone have a fix for it?

Have you tried going into the properties of portal 2 and opting in for a beta? I think there is a beta you can opt in for that is 1 build before the latest one. Meaning it's 1 update behind.

[Kefty]

I've already tried that sadly

[AndyTheMusicNerd]

Hmm, have you used any mods, such as beemod, or SAR? Cause I experienced crashes when I had multiple mods like that running, and I had to manually uninstall, then reinstall portal 2.

[AndyTheMusicNerd]

Community mods, such as Aperture tag, Portal reloaded, etc shouldn't affect starting it.

No i never touched mods with this game, I have played portal stories and I tried to play portal reloaded but that's when i noticed my portal wasn't working

[AndyTheMusicNerd]

So if you are trying to play portal reloaded and you have multiple hard drives, you need to make sure that portal 2 and portal reloaded (or any other community mod) is on the same drive. You don't necessarily have to uninstall and reinstall it on a different drive, you can just copy paste it to the other drive and it should recognize the game files.

Another thing to add, If you have the Razer Hydra DLC for portal 2, make sure that isn't installed, cause that could cause problems for the game running!

I also have the same problem just trying to load portal without any mods at all. Started happening since I upgraded to a 3080. I have tried reinstalling, verifying cache etc but nothing so far :(

This has happened to me a few times in the last few days (OS:Ubuntu 20.1) normal file validation does not seem to help, but both times its been fixed by opting into Portal 2 limited beta and then going back to no beta. I suspect its something to do with downloaded maps because it never happened when playing the default story.

If you ever find a fix please let me know, my discord is kefty#4932

Getting the same exact issue as the one mentioned above by Kefty. Have uninstalled and reinstalled the game, powercycled, tried the compatibility mode "fix," have tried running as administrator... Nothing. The game simply decided it does not want to open. Does precisely what Kefty's does in their provided link. Rather annoying to suddenly be unable to play the game.

I believe I've found a fix, or maybe a cause of the issue?

I am (and have been) experiencing the same issues. My specs are as follows:
Windows 10 / Ryzen 5 3600x / 2060 Super / 3200 16gb / 3 Monitors (2 display port, 1 HDMI)

I tried the "compatibility mode" fix, I tried running as administrator, I tried power cycling, uninstalling and reinstalling... I abandoned all my mods and workshop files to try and fix the game. It's incredibly frustrating that if you google around, you'll not find any information about the latest issue. This DOES seem, by the way, to be a recent issue.

How did I fix it? I unplugged my HDMI monitor. I'm not kidding.

Annoyingly, and maybe somebody more intelligent can explain why - when my display port monitors are off, my computer does not recognize them as being plugged in. The HDMI monitor, on the other hand, whether off or not, is still recognized (and sometimes even utilized) by certain programs. I run into issues with VLC opening on the (often switched off) HDMI monitor, Windows Explorer, Discord... and I think in this case, Portal 2 is also prioritizing my (powered off, but plugged in) HDMI monitor.

The fix was to literally unplug the HDMI cable from the monitor. Soon as I did, the game opened up just fine. Hope this helps some of you, and I'll try to maybe report it as a bug if the developers are even still interested in our niche hardware issues.

Well this fix seemed so crazy and out of the blue I figured it just had to work but sadly this doesn't seem to be the issue with it on my PC. I'm running two monitors and I tried every combination of cords being plugged and un-plugged on my monitors to try and get it to work but none of them seemed to work, I think i'm going to try a different cord and see if that for some reason fixes it.
