Hey, everyone. I’ve recently been toying around with an Unreal Engine 5 project that I built using the third person template, and I noticed that the editor (placing objects and flying around the map) worked fine, but whenever I launch a playtest, the engine just crashes. I’ve updated my GPU drivers (I run an AMD Radeon RX 6700 XT, an Intel Core i7-8700, and 64GB of DDR4-2666 in my system if that helps) I also make sure to check every time that I have no other apps running in the background, but no matter what, playtesting always crashes the engine, usually within five seconds.
When it crashes, where in the code does it crash?
You need to get a stack trace, and ideally, connect with a debugger (or start the game from a debugger) so you can debug it.
I dunno, man. I haven’t even built any mechanics into my game yet, I’ve just been importing assets.
And by the way, wdym by debugger? Like a hardware-based one like an XDK or something software-based?
Hey there @sergiva_ms! Welcome to the community! It does sound like there’s a possible environmental issue at play here if any Play in Editor (PIE for short) is crashing. Depending on your technical expertise, I usually recommend before we get into attaching a debugger, we can check out the crash context with the editor symbols installed to get glimpse at what the issue could be. This video goes over how to install those editor symbols and a bit more useful information. Once you receive that crash context, we could take a look at the log here.

By “debugger” I mean a “debugger.” As in “attach to process” or “launch process” in the Visual Studio IDE or the Visual Studio Code IDE.
If you don’t know how to start a program with debugging in your IDE of choice, I recommend reading up on how to do that, it’s a fundamental part of the programmers toolset.
Haven’t attached a debugger yet, but I just crashed the engine, and the message logs gave me this:
Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000018

Any idea what it means?
Looks like you’re using the unreal editor, and something is getting a NULL pointer.
If this is from a packaged game, then the problem is that you’re trying to use editor APIs from a packaged game, where the editor infrastructure isn’t available.
Haven’t packaged it to a .exe yet.
