Outlook 2019 C2R crashes when I try to manage Rules and Warnings

Hi All,

After Office 2019 C2R updated itself from version 16.0.12827.20470 to the latest version, Outlook 2019 crashes on several Windows 10 Pro PC's when I select Rules -> Manage Rules and Warnings. When I restore Outlook back to the previous version 16.0.12827.20470 I can edit and add rules without any problem.
Restoring to the previous version is done through the command officec2rclient.exe /update user updatetoversion=16.0.12827.20470

I have searched the internet for this issue quite some time now, but although it is mentioned a couple of times, there seems to be no solution to resolve this.

On one of the PC's I have already tried a lot to solve this, including repairing office, creating a new profile but none of them resolved this rules issue.
I use several POP3 and IMAP accounts as well as quite a lot of rules.

I have attached a screenshot of the viewer for diagnostic information regarding the crash, maybe that will put somebody on the right track.
Does anyone have seen this issue before and (even better) knows a solution for this issue?

I would really appreciate help with this.

    Thanks everybody for sharing all their efforts and findings to figure out why Outlook 2019 was crashing when editing rules.

    Based on the acknowledge of the fix by several users, that were facing this issue, we can now safely say that Microsoft solved this problem starting with Outlook version 2102 build 13801.20266

    @Bob Zeidman
    Let me know if the problem still existst after you upgrade your Windows 10 Pro version 2004 to the newest version 20H2 (easy upgrade).

    @Jos de Vries :

    I just upgraded to the latest Windows according to my Windows Update feature. It's not version 2004. It's Windows 10 Pro Version 20H2, installed on 6/25/2020, OS Build 19042.630, Windows Feature Experience Pack 120.2212.310. Outlook is still crashing when changing the rules.

    How do I upgrade to Windows 10 Pro Version 2004?

    Dear Friends,
    I had the support of Microsoft 2 hours today and finally we identified the root cause (at least for me).
    This root cause will be escalated to Outlook application roadmap managers.
    My outlook version is the latest one.
    The Outlook client was crashing because I established some rule like 'for the specific account"contact@sn .com"' and 2 accounts were batched together at the mail rules root (contact@sn .com + contact@pop3.com). This was causing to force the adoption of condition "for this computer only" and was causing the crash.
    Not sure if you have the same problem but at least for me this workaround resolved the issue, until Outlook engineers deploy a version which fixes the issue (2 Account batched together).
    Best regards. François
