Disable or Readjust All Your Overclock Settings

Even if Last Epoch isn't your most demanding game you should check your OC settings.

Turn off any GPU, CPU, or RAM overclocking.
Launch Last Epoch and see if you are still getting a black screen.
If disabling overclocking resolves the problem, reconsider your overclock settings. Starting with GPU, then CPU, and finally RAM.
When you get stable settings you should be able to play without any future problems, though future game updates may change things so keep an eye on it.

Use DDU to Clean install GPU Drivers.

As these two problems are almost always caused by bad, outdated, or corrupted GPU drivers, clean installing your drivers with DDU will usually fix Last Epoch stuck, black screen and crashing problems. And might even fix Last Epoch's low fps drops

Download Display Driver Uninstaller
Download the latest GPU driver you want to use.
Now Disable your Internet connection.
Run DDU and select the option to remove GeForce Experience (GFE) if prompted. You will get a similar message if you are using AMD Graphics.
After the process completes accept the restart request and let your computer restart.
Now install the driver software and re-establish your internet connection. This prevents Windows from installing generic drivers automatically.
Now that you have new drivers everything should be working!

Use FSR or DLSS in Last Epoch

Enable DLSS, FSR and even frame generation if your device supports it.
Start Last Epoch with the lowest graphics settings possible. But keep your screen resolution set how you want it.
Gradually increase graphics settings until you find a setting you are happy with that works without black screening.

It Might be Time to Abandon those Mods for a While.

Mods are awesome! But mods are problematic! So here's what you need to do.

If you're using mods, disable them. If the game works you’ve found your problem. Stop using those mods for a while.
Try launching Last Epoch without any mods enabled.
If Last Epoch launches successfully without mods, enable your mods one by one. Launch the game after enabling each mod to identify the one causing conflicts.
Ensure your mods are up to date and compatible with the game's current version.
