hi @Majorrblues ,

The log before the crash says

[2026.01.27-13.53.31:076][926]LogAssetRegistry: Error: Package is unloadable: C:/Users/oibaf/Documents/Fortnite Projects/trying/Content/ExternalActors/trying/5/W2/ **B781WPOXYARM192MNVYO98**.uasset.

_Reason: **Invalid value** for PACKAGE\_FILE\_TAG at start of file._

Try putting **B781WPOXYARM192MNVYO98** search box of the Asset box to find the asset then delete this

The alternative is Win File explorer and find the asset above and delete the asset

The probable cause is the dimensions are not the power of two
