Conflict with Sentinel Agent: COMBASE.DLL STATUS_ACCESS_VIOLATION

Problem

At some point after working with the internal datasheet of think-cell I receive a COMBASE.DLL STATUS_ACCESS_VIOLATION error message.

Reproduction Steps

1. Open PowerPoint

2. Insert think-cell stacked chart:
   Insert → think-cell → Elements → Stacked → click on slide to insert chart
   → internal datasheet opens (Excel process shown in Task Manager → (More Details) → Details)

3. Close internal datasheet
   → Wait until Excel process closes in Task Manager → (More Details) → Details) (may take ~30s)
   → CRITICALWITHMSG COMBASE.DLL 10.0.18362.1645+0x1BEBBE: STATUS_ACCESS_VIOLATION
   → After dismissing error message, Excel process is closed

Analysis

Ask your internal IT team to temporarily deactivate / uninstall Sentinel Agent and check if the issue continues to occur.

Workaround

Create an Interoperability – Extended exclusion in Sentinel Agent for the file: C:\WINDOWS\System32\combase.dll.
