Cook failing on QueuedRequests.Num() == 0

I’m currently having probems with cooking my project, every attempt generates the following error: “Ensure condition failed: QueuedRequests.Num() == 0”

I’m running a Unreal Engine 4.26.2 project using both BP and c++ with the following plugins: GameplayAbilities, EasyMultiSave, NodeGraphAssistant, Water and GridBasedTileEditingSystem. On Windows 10 using visual studio community 2019 16.11.18.

Usually I have been able to make something out of the errors generated but this is giving me nothing that I can work with. So it’s failing the ensure macro at line 1557 in BlueprintCompilationManager.cpp because (QueuedRequests.Num() == 0) condition is true. I can’t seem to find any information online about QueuedRequests, does anyone here have any knowlegde about this or have run into a similar problem?

The problem ended up being a blueprint submitted with, according to unreal editor, no changes to Perforce. Had to go through all files within all revisions in Perforce depot but when the problematic blueprint got reverted it just started working again with the cook. Really frustrating and time consuming problem.
