Unreal Engine is Crashing due to D3D device being lost

Hello!

Me and two other students are working together on a game using github. I setup the project and ever since the beginning my two team mates are continuously crashing when working. It appears to be linked to saving or changing file names.
Here is the following Error message:

Fatal error: [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Windows/D3D11RHI/Private/D3D11Util.cpp] [Line: 198] Unreal Engine is exiting due to D3D device being lost. (Error: 0x887A0020 - ‘INTERNAL_ERROR’)

Any help would be much appreciated.
