System.NullReferenceException when opening a .uasset file

[MarcosVLl2]

Tried to open some files from the game Will To Live Online, found myself with error System.NullReferenceException in line 203 of MainSerializer.cs

Steps to reproduce the behavior:

1. Open UAssetGUI.exe
2. Set UE4 version to 4.26
3. Open file "NPS_TeleportCCD"
4. Error!

Expected behavior
The file opens up correctly and I can see it
