I get an error 0x887A0005 while playing Apex Legends.

@Angel_Shoot_1682 This seems to be an issue with your GPU.

You should check to make sure your GPU's drivers is fully updated. (If it is fully updated, I would try reinstalling the drivers).

It might be worth checking the GPU's connections to your PC's Motherboard to make sure its all plugged in correctly, (as well as making sure its not damaged or badly bent in any way). You should also check to make sure the fans on your GPU is still working as well as removing any dust you find.

Its also possible that the problem is caused by an issue with your PC's power supply, part of the PC's hardware had gone bad, (due to wear and tear), conflicts between the GPU and other system drivers, and/or from overclocking your GPU.

Besides checking for an update for your GPU, (I would also update Windows if it has any updates), you could check to see if your GPU is overheating, check your power supply, disable overclocking, (if its enabled), and run diagnostics on your PC's hardware.

You could also try repairing the system's files, and see if that helps resolve the issue.

To repair your system's files:

Note: Considering that you could play the game for 2-3 hours before having an issue with the GPU, it might be an overheating issue with the GPU, (possibly a fan had stopped working, there's a build up of dust, or maybe even a hardware issue), so you should start with checking to see if the GPU is overheating, and making sure its fully plugged in and is not damaged or badly bent.
