After the Microsoft Office updates 3 days ago, Outlook becomes unresponsive with Endpoint Security

[Mitja-S3NEXT]

After the Microsoft Office updates 3 days ago, some different useres (not same customers) reported that the Outlook app is starting to become unresponsive on some tasks, like forwarding messages.

Outlook version : 2019

Windows version : 11 Pro

CheckPoint Endpoint Security Advanced version : 86.80.0109  (latest Recommended)

After disabling the AntiMalware deployment blade :  Outlook is still unresponsive on some tasks

After disabling the Threat Emulation and Anti Exploit deployment blade :  Outlook works fine with no problems

Do symptoms resolve simply by disabling the outlook add-in  per sk175845 or no?

If not already please report this via TAC for further investigation.

This exception was inserted (see screenshot), but it did not solve the problem.

This is also a massive issue for us.

Outlook and Excel consistently crashing. We know it is checkpoint doing this, as we have uninstalled the AV and the problems stop. It is very intermittent however very consistent and annoying. We've had it reported on around 20 users out of 300. After 2 months still no fix?
