Project from an old version of UE4 won't start up; can't compile, plugin dependency issue possibly?

Hello,

The issue I’m facing stems from me not regularly updating or upgrading my project. It’s been a couple of months since its last development, and I’m unsure of how to open the project. I receive the following error when I attempt to open my old project, after attempting to convert it to 4.23.

Running C:/Program Files/Epic Games/UE_4.23/Engine/Binaries/DotNET/UnrealBuildTool.exe Development Win64 -Project=“D:/Wander 4.23 - 4/Wander.uproject” -TargetType=Editor -Progress -NoHotReloadFromIDE
Creating makefile for UE4Editor (no existing makefile)
ERROR: Unable to find plugin ‘DirGravity’ (referenced via Wander.uproject). Install it and try again, or remove it from the required plugin list.

I’m unsure of how to proceed; and don’t know how to remove that plugin from the plugins list without doing opening the project itself. What should I do?

Bump. Any idea what could possibly be causing this, or where I could get some help?
