I’ve wanted to start learning UE5 but i’ve a big issue, when i’m opening a new window for example if i want to bring a starter content to a project the window is going to glitch and blink and when i’m closing that window UE5 crash with that error :
can you be more specific with your steps:
which windows (the ContentBrowser/ContentDrawer , the Project creation window, the Blueprint Editor…)
can you tell, or show the steps that produce the issue?
is this in a new project, a blank project, a project you have been working on for a while?
is this project in just Blueprints, or is there custom C++ involved?
did you add any plugins to the project?
what is your operating system?
does this happen when you launch the project from the Epic Games Launcher, from the Editor Project Picker (probably the icon on your desktop, or taskbar), or when you launch the project directly from the [ProjectName].uproject?
in the Launcher for the tile of your engine version click the down-arrow->Options. In the box that appears make sure that “Source Code” (this might already be checked so leave it if it is), and “Editor Symbols for Debugging” are checked. this way when you do get a crash report/StackTrace the report will tell us what function lines are actually involved.
then attempt to do the task and see if the issue persists, and provide that stack trace.
you can try in the Epic Games Launcher, the tile for your engine version the down Arrow->“Verify”. this will attempt to do a checksum on all the files that were installed with the engine, and reacquire any that are missing or fail the checksum.
Yes. UE5 crashes almost very oftenly without any reason, since late Oct 2025. And trying to re-install to other version of UE5, the Epic Launcher is just not able to download any things, every things are just not working at all !
“THIS IS A REALLY SERIUS PROBLEM FOR THE GAME & ENTERTAINMENT INDUSTRY WHO ARE COUNTING ON USING EPIC UNREAL”
Especially, after latest Windows updates 25H2, such ‘crashes’ had even happened to not just UE5 but plus a lot of my Steam games & Windows itself starts to behave strangely - they could just crashed with black screen without any reason. A lot due to “Not enough video memory or No video memory are allocated” problems. Perhaps, these problems would be gone after Microsoft & nVidia have come up next problem solving patches.
those that use these forums will tend to be the non-enterprise users, so “the Game and Entertainment industry” will not be impacted as much as you think.
if the majority of the issues are after the windows update then that is much more likely the culprit, especially if it is hitter other software.
if you are experiencing a “Not enough Video memory” and you are not actually setting options in the software that would do so, then you need to do a RAM integrity check (typically a BIOS level utility and takes minutes per GB of RAM), or a problem with your CPU: if you have an Intel 13XXX, or 14XXX these had degradation issues because of manufacture defects, and “normal” voltages. “Not enough Video memory” or “out of Video Memory” was a leading indicator that the damage had been done, and the CPU either needed to be undervolted, or replaced.
Windows 11 25H2 is a separate issue based on the stability of Windows as a platform, and it brought to light issues with some SSDs, mostly on how the controller behaves when it hits it cache limit.
All of these would be well outside the scope of these forums, and might not be related to Soonsano’s issue.
