I’m crashing constantly using UEFN, usually within 10 seconds of opening any project. These consistent crashes started happening yesterday after attempting to create a new template “Verse Device Starter” project. During creation of that project while it was opening, UEFN crashed. Every time I opened UEFN after that it almost immediately crashed. I deleted the project locally, and several times after that just opening the “New/Open Project” dialog UEFN would crash immediately. I finally got through after several tries to create a new island and could run UEFN for minutes at a time, but crashes continued. Later in the day however the crashes were almost immediately on opening the project again.
Today I’ve tried deleting all my local project directories, I uninstalled FortnitePublicTest and reinstalled, and I created a new blank project without source control enabled. It crashes on launch immediately every time still.
It seems we are unable to delete remote projects currently, so maybe staff could manually delete those and see if that resolves my issue? Any other ideas or workarounds appreciated.
Actually I think I managed to hunt down your crash reports . It seems we already have an internal ticket for something similar (if not identical to your issue). It looks like you’re using a laptop with an Nvidia GPU? If so there’s a comment on the Jira ticket that might help:
Ah, so this is a laptop with an nvidia GPU? Can you make sure that the drivers for the integrated Intel GPU are up to date? Unreal doesn’t use the integrated GPU if there’s a discrete one, but in most laptops, the output ports are controlled by that, so the system must transfer the image rendered by the nvidia chip to the intel chip to send it out to an external monitor. Havin outdated drivers can cause trouble in that case.
If that doesn’t help we can keep investigating but know that we’re aware of these crashes and we’ll keep you updated on potential fixes. As a possible workaround if you’re using an external monitor could you try disconnecting the external monitor and see if that helps your crashes? Thanks!!
Update 2: It appears that forcing UEFN to use your dedicated Nvidia GPU might resolve the issues. You can force UEFN to use the dedicated GPU through the Nvidia control panel. Switching to Your PC's Dedicated GPU | Ubisoft Help Though please still make sure your intel GPU drivers are up to date as they can cause issues.
I did find a similar post here: ue5 crashing, anyone can help me?
That looks like the same error, but resetting all Nvidia control settings to default did not fix it.
I am on a laptop with Nvidia GPU with 2 external monitors.
I was able to narrow down exactly to where my crash was happening I believe. It seems it 100% crashes whenever I close the “New/Open project” dialog. Because I didn’t have “open last project on startup” selected, immediately after choosing my project to open it would crash because that dialog would close. I have a work around at least now to enable “open last project on startup” so that dialog doesn’t open.
It does also seem related to external monitors like you mention, when UEFN opens, I often drag it from the laptop primary display onto one of the external monitors.
My integrated and Nvidia GPU drivers are up to date.
I’ll try to force UEFN to use Nvidia through the control panel now.
Then I disconnected my external monitors, and UEFN does not crash any more when closing the dialog with the external monitors disconnected. Reconnecting the monitors and trying to open and close the dialog still did not crash UEFN.
With the monitors still connected I closed and re-opened UEFN, and at that point closing the “New/Open Project” dialog the crashes started again.
So if I open UEFN with no external monitors connected it seems to not crash. But with external monitors connected it will crash, even with forcing Nvidia GPU (unless I’ve done that incorrectly).
@Trent_RED out of curiosity did you need to update your integrated GPU drivers when you checked them? I only ask because someone on the team mentioned that your integrated GPU drivers were old. If so, that’s great. Otherwise we can discuss how to upgrade/find the latest versions.
Other than that I’ve relayed your information to someone who can help. If I hear anything back I’ll update you asap. Thanks!
I did not actually update my integrated GPU drivers earlier when checked. I checked in device manager to automatically update and it said I had latest, I had no Windows Updates available, and in “Intel Graphics Command Center” it said it was latest drivers as well.
But I’ve now checked Intel’s site and found that there actually was newer drivers and manually updated my driver:
Unfortunately I’m seeing the same crash on closing the “New/Open Project” dialog after updating and restarting.
I can work around this by just not opening that dialog for now, but any other info I can give to help let me know.
