I wanted to provide a quick update regarding this issue with Unreal Engine.
I have now tested the latest update (5.7.4), but unfortunately the problem still persists. The engine continues to freeze at around 74% during the plugin initialization phase, exactly like in the previous versions. The behavior remains inconsistent in terms of which plugin is displayed during the freeze, which suggests the problem may be happening during the plugin loading process itself rather than being tied to a specific plugin.
At the moment, the only stable solution for me is to keep working in UE 5.6, which runs perfectly on the same system.
If anyone from the community—or ideally engineers from Epic—has insight into what might be happening in the plugin initialization stage in 5.7, I would greatly appreciate any guidance on further diagnostics (logs, launch flags, debug methods, etc.).
Thank you in advance for any help.
Update – Issue Resolved
I would like to share the solution in case someone else encounters the same problem with Unreal Engine.
The engine was consistently freezing at around 74% during the “Loading Plugins” stage in version 5.7.x. The plugin shown during the freeze changed between launches, which made the issue difficult to diagnose. The editor became “Not Responding” and no crash report appeared.
After analyzing the log file, it turned out that the freeze occurred during the initialization of the StylusInput / Wintab system.
The root cause was a graphics tablet driver installed on my system. Once I uninstalled the tablet software, Unreal Engine started normally and the problem completely disappeared.
So if anyone experiences a similar freeze during plugin initialization, it may be worth checking for tablet or stylus drivers (Wacom, Huion, XP-Pen, etc.) that interact with the Wintab API.
Thanks to everyone who took the time to read and help.
