How does Path of Building behave?

I'm getting constant OnFrame errors with the latest version of PoB. This happens on all screens, including the builds index. A stack trace as an example from the Build index screen.

Error:

In 'OnFrame': Modules/ModParser.lua:6364: calling 'find' on bad self (string expected, got nil)
stack traceback:
	[C]: in function 'find'
	Modules/ModParser.lua:6364: in function 'scan'
	Modules/ModParser.lua:6498: in function 'parseMod'
	Modules/ModParser.lua:6744: in function 'parseMod'
	Classes/Item.lua:743: in function 'ParseRaw'
	Classes/ItemsTab.lua:1036: in function <Classes/ItemsTab.lua:1004>

	Modules/Main.lua:354: in function <Modules/Main.lua:340>

A stack trace while viewing the calc tab.

Error:

In 'OnFrame': Classes/CalcSectionControl.lua:291: attempt to index field 'calcsTab' (a trace value)
stack traceback:
	Classes/CalcSectionControl.lua:291: in function 'Draw'
	Classes/ControlHost.lua:91: in function 'DrawControls'
	Classes/CalcsTab.lua:342: in function 'Draw'

v2.63.0 master
Press Enter/Escape to dismiss, or F5 to restart the application.
Press CTRL + C to copy error text.

This is occurring at a fairly constant rate to the point that it's relatively unusable. (Every few seconds, I imagine as part of the UI loop).

I have attempted an uninstall / reinstall but the behaviour / bug has persisted.

How to reproduce the issue

No set behavior appears to trigger this behavior, in that I can't mouse over a particular field and trigger it constantly. It does appear to occur when interacting with the program, navigating around menus, etc.

Beginne damit, die beiden Stacktraces in Modules/ModParser.lua:6364 und Classes/CalcSectionControl.lua:291 zu prüfen, und verfolge anschließend ihre Aufrufer durch Classes/Item.lua, Classes/ItemsTab.lua, Classes/CalcsTab.lua und Launch.lua:111. Reproduziere die Fehler beim Navigieren durch Menüs, den Build-Index und den Calc-Tab; abgeschlossen ist die Aufgabe, wenn normale Interaktion keine wiederkehrenden OnFrame-Abstürze mehr verursacht.
