Plugin not loading in

[Alienprodigy]

Version 4.3.1.11, tried updating to 5.3.0.2, however this doesn't seem to work.

When booting up Lightroom the plugin doesn't load in, the usually window doesn't pop up. When checking under plugin manager it states the plugin is installed and running.

When disabling, then enabling the app, then hitting reload plugin, the following errors show up:
Plug-in error log for plug-in at: C:\Program Files\Adobe\Adobe Lightroom Classic\MIDI2LR.lrplugin

**** Error 1

An error occurred while attempting to run one of the plug-in’s scripts.
?:0: attempt to call method 'send' (a nil value)

**** Error 2

An error occurred while attempting to shut down the plugin.
