First, you should try running the game launcher as an administrator on Windows to allow the launcher program and the game files to run properly.

Now, select Properties > Click on the Compatibility tab.

Make sure to click on the Run this program as an administrator checkbox to checkmark it.
Click on Apply and select OK to save changes.
Now, you can just double-click on the game exe file to launch it.

Right-click on the Start Menu to open up the Quick Access Menu.
Click on Device Manager from the list to open the interface.
Now, you’ll need to double-click on Display adapters to expand it.

Device Manager Update Display Adapter

Then right-click on the dedicated graphics card that’s active.
Next, click on Update driver > Choose Search automatically for drivers.
The system will automatically check for the available update.

3. End Background Processes

Multiple affected players have started reporting that Steam overlay is running in the background which is troubling a lot. In-Game overlay apps may consume higher system resources which can easily trigger issues with the game launching.

Open the Steam client > Go to Library.
Now, right-click on Last of Us Part 1 > Select Properties.
Head over to the General section > Here just uncheck the Enable the Steam Overlay while in-game checkbox.
Go back to Library > Launch Last of Us Part 1 to check if the game is still not launching.

Right-click on Last of Us Part 1 > Click on Controller.
Set ‘OVERRIDE FOR Last of Us Part 1’ to ‘Disable Steam Input’.

Click on the Windows icon to open the Start Menu > Type %LOCALAPPDATA% on the search bar and open it.
Go to the %LOCALAPPDATA% folder > Search for the ‘Prospect’ folder.
Open the mentioned folder and go to the Saved > Config > WindowsNoEditor directory.
Under the WindowsNoEditor folder, you’ll find a file called ‘GameUserSettings’.
Open the user settings file using any text editor > Set ‘FullscreenMode=1’ to ‘FullscreenMode=0’ to save changes.
Finally, try launching the game again to check for the issue.

7. Disable DirectX 12

If you use DirectX 12 on the PC, you can try turning it off. As the DirectX 12 version is the latest one available for Windows, it may be possible that your PC configuration isn’t capable of running it. To turn it off:

9. Disable Multi-Threaded Rendering

It seems that the in-game video settings menu in the Last of Us Part 1 title has a multi-threaded rendering option enabled, somehow conflicting with the game crashing quite often. Make sure to disable the multi-threaded rendering option from the game menu to try resolving the issue. If using an AMD processor, turn it off and reboot the game to apply changes.

Now, click on the Open Windows Security button.
Go to Virus & threat protection > Click on Manage settings.

If you’re using any other antivirus program on your PC, then turn it off. However, if you’re not interested in disabling the antivirus software on the PC, you can just whitelist the game files to the antivirus software. To do that:

Open the Steam client > Go to Library.
Click on Last of Us Part 1 from the list of installed games.
Now, click on the Settings icon next to Last of Us Part 1 game page.
Click on Manage > Go to Browse local files.
Next, open the Prospect folder > Binaries > Win64.
