Occasional Exception when Closing Word

I'm using Delphi 10.1 with an ADX add-in.
Ever since I started using an embedded Excel object I started getting occasional exceptions (maybe 1 in 20) when closing Word (see below).
I assume it's some sort of timing issue - maybe I'm doing something wrong. Could you give me any pointers?
Thanks

Hello Mark,

We only have generic suggestions. Release COM objects and disconnect form events. You may want to use EurekaLog to locate the issue.

Hi Andrei
Thanks. In the end I contacted https://www.devexpress.com/Support/Center/Question/Details/T525649/exceptions-in-addinexpress-dll-during-finalization and they came up with a modification to one of their finalization routines (in dxDPIAwareUtils).
It seems to have done the trick. Since then I haven't had any similar issues.
