(and have already tried launching the game with "-disablemodding" in the launch options)
It might be that your save has somehow become corrupt Try the following:
Try launching the game: You should be able to go past the Press any key screen now - and the game should launch the tutorial.
Once you have loaded the spacerig go to the ESC menu
Select a recent save from the list and let it overwrite your current save.
It will restore your save to the selected save and you should be good to go from there
Occasionally, a connection issue between Steam and the game may be preventing you from playing. This is indicated by a loading screen with the text "Waiting for Steam to load"
First of all; try to restart your PC. If that doesn't resolve it, end all Steam related processes via the Task Manager and restart Steam. Ensure Steam isn't at fault by messaging someone on your friends list. Did your friend receive your chat message? Perfect. You have a connection to Steam. Boot up the game and see if your issue has been fixed.
If that doesn't resolve it head into the quarantine settings of your anti-virus and restore all DRG-related files that may have been caught in the quarantine. Closing your anti-virus or adding an exception for the game in the settings is rarely sufficient. You must ensure that no DRG related files have already been isolated in the quarantine.
Last but not least, running dedicated servers for other games can be the cause of a connection conflict. Close any dedicated servers that may be running in the background and see if that fixes your issue. This has for instance been the case for players running Mordhau servers and Conan Exiles servers.
For those of you affected by the 2015 C++ Runtime Bug that is causing the game not to run for you, we may have a solution. Try out the below steps as we've been able to remedy this issue on our end with these methods.
If you have Windows 7, it can be resolved by ensuring that you have Service Pack 1 installed, and then additionally installing this update manually:

If you have Windows 8.1, you may require this update:

Once those are installed and you’ve rebooted, uninstall and reinstall the game. It should permit the 2015 runtime to successfully install.
If the game refuses to launch entirely even after reinstalling, try to download DirectX directly from Microsoft's website. https://www.microsoft.com/en-ca/download/details.aspx?id=35
DRG uses DirectX 12 by default. Some players have to start the game forcing a specific version of DirectX. To make it easier to do this for everyone, we introduced a popup when you launch the game. It gives you three options
Play Deep Rock Galactic: Uses the last chosen setting. If you haven’t chosen a specific version of DirectX before then it defaults to DirectX 12. This is also the mode the game is launched in via the desktop shortcut.
Play Deep Rock Galactic (DirectX 12): Starts the game using DirectX 12
Play Deep Rock Galactic (DirectX 11): Starts the game using DirectX 11
The first option might seem superfluous, but we added it for two reasons: To make subsequent startups easier by letting you just click ‘play’ if you already selected the version of DirectX you want to use You don’t get this popup when using a desktop shortcut, it uses the first option by default. So you can set the game to start with your preferred version of DirectX by launching it through steam once and then keep using a desktop shortcut after that.
If the game crashes on startup, try to add "-regenerateinis" to the launch options by right-clicking the game in your Steam Library > Properties > Set Launch Options. Beware that this launch option will reset all options to their defaults.
