Can't anymore drop a mesh in the viewport

From Yesterday eve, every time I drag and drop an object form content browser, to the viewport, the engine crashes without a reason, no matter which object/folder/whatever, it just crashes, I didn’t install any pack/plugin/whatever. This is the error, Thanks who will help.

Assertion failed: !FUObjectThreadContext::Get().IsRoutingPostLoad [File:D:\Build++UE4\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\ScriptCore.cpp] [Line: 1320] Cannot call UnrealScript (WBP_Task_C /Game/Exodus_Project/Livelli/TrailerTeaser.TrailerTeaser:WBP_Task_C_14 - Function /FixThis/Widgets/WBP_Task.WBP_Task_C:BP_SetText) while PostLoading objects,

I think is related to the FixTHis plugin, but i didn’t change/mess/upgrde it…

Thanks.

Disabling The plugin, make the engine work again…
I submitted the many crash reports anyway. So if this happens to you. disable and reenable the plugin.

(edit)

Anyway doing this you gonna lose all your previous FixThis notes :frowning:
