Engine crashing when opening or hovering over collapsed graph

Currently experiencing this issue that popped up out of nowhere, a few of my collapsed graphs that I knew worked 100% before are now crashing the entire engine whenever I hover over them or open them.
The crash error I get is:

“Assertion failed: OutPin->LinkedTo.Num() == 1 [File:D:/Build/++UE4/Sync/Engine/Source/Editor/GraphEditor/Private/BlueprintConnectionDrawingPolicy.cpp] [Line: 506]” Some of the ones that have a crash occuring I can hover over, but will crash upon expanding. Any help with this would be very very much appreciated.

This has been tested on both 4.24 and 4.26 and the issue is occuring on both.

This is causing me to be unable to recover significant chunks of my work.
