ISSUE: Failed to Convert - Path does not map to any roots since using in-world Widgets + Major spike in Memory usage

Summary

See the below error that keeps crashing my project. I have restarted now for almost 7th time.

Fatal error: [File:Z:\UEVFS\Root\Engine\Source\Runtime\CoreUObject\Private\Misc\PackageName.cpp] [Line: 1442]
LongPackageNameToFilename failed to convert ‘/FNEGothicFonts/Fonts/SerifGothicStd-Heavy’. Path does not map to any roots.

I think it has to do after using in-world UMG widgets in my project. Since then, there is a major spike in memory usage, and I keep getting this error before the project crashes.

Anyone else having a similar issue?

I need urgent help with this, since this project is for Creatures that supposed to launch on 23 July.

Thanks in advance.

Steps to Reproduce

I am not sure. My computer keeps crashing. Almost 7 times. Mostly it started happening after starting to use UMG widgets in world. There is also now a big spike in memory everytime I am in the project. Usually around 8,000M but now 13,000M and that is without any asset additions.

Expected Result

The project works for a while, but then seems to run out of memory, and then this weird error appears: Fatal error: [File:Z:\UEVFS\Root\Engine\Source\Runtime\CoreUObject\Private\Misc\PackageName.cpp] [Line: 1442]
LongPackageNameToFilename failed to convert ‘/FNEGothicFonts/Fonts/SerifGothicStd-Heavy’. Path does not map to any roots.

It says something about the font. Maybe there is a bug in UMG widgets using this font.

Observed Result

Computer crashes as memory spikes majorly. Looks like after using in-world UMG widgets.

Platform(s)

UEFN.

@Flak Good Morning. Could I get support on this issue as I’m struggling to complete the island. The editor closes almost 10+ times a day now.
