I have a Binary Build of a project that runs perfectly fine on a colleagues machine but as soon as we try to run it on my machine we get the following error: Assertion failed: !Singleton

Assertion failed: !Singleton [File:D:\Build++UE4+Release-4.16+Compile\Sync\Engine\Source\Runtime\Core\Private\Internationalization\ICUBreakIterator.cpp] [Line: 15]

This is weird because the D drive refers to my DVD drive and the project actually runs on my E Drive. I have attached the XML Crash Log and the Minidump file.

I have now tried with a Source Code Build as well … and I get the same error. I used this commit: 484ae229d4d8457c916b90b1b00d829ac61e75ce

This turned out to be a corrupt install on my side caused by source code. I have resolved this issue.
