Application Error SDXHelper.exe module ntdll.dll

I'm wondering if anyone out there can help me with a re-occurring event that I'm getting on my Windows Server 2012 R2 RDS Servers. The servers are running Office 365 ProPlus Version 2003 (Build 12624.20466 Click-to-Run) Monthly Channel.

I used to get the event every now and then. However, its popped up every day for the last 4 days. The timings don't appear to have a pattern with some happening in the morning, late morning, mid day, and afternoon so I don't think this error is related to a certain user pattern.

I've performed an sfc /VERIFYFILE="c:\windows\system32\ntdll.dll" and it has come back with no issues with the .ddl file. Has anyone else run into this issue before?

Office 365 is not supported on Windows Server 2012 R2, weird behavior is expected in these conditions. You should upgrade to Windows Server 2019.
