Excel VSTO Application.Addins Object is very Slow

Question

Hi Team,

We have developed the Excel VSTO add-in, in startup code we have a code to check our add-in (.xlam) is loaded or not by using Globals.ThisAddin.Application.Addins object, for the last 2 weeks accessing this (Addins) object is very slow (taking around 12 secs) in certain windows 10 systems.

Our M365 version is M365 MSO V2308 Build 16.0.16731.20822 (32 Bit)

Many thanks

Kathir
