M1 Mac AnyConnect 4.10.05095 Unable to load the CSD Library

[arg3x]

We just started deploying AnyConnect 4.10.05095 and we're running into a problem with M1 Macs. One of the connection profiles is for our higher security VPN which does a posture check using OPSWAT. When Intel Macs use this profile, it works just fine. When M1 Mac use this profile they get the following error message, "Posture Assessment Failed": Unable to load the CSD library".  These same users don't run into a problem when installing 4.10.01075. It apparently gives the error message with 4.10.04071 as well. 

Has anyone else run into this problem?

Followup - I had the user run DART, and I see this entry:

This is most likely a compatibility issue between AnyConnect image and HostScan package on the headend. Take a look at the following table from the AnyConnect release notes.

You need at least HostScan 4.10.02086 configured on the headend if you have AnyConnect 4.10.2086 or later.

Thanks for the solution, we also had a problem with the library on the study laptop, we could not figure out how to solve this problem.

Thank you - that turned out to be the problem. I had read the release notes, but clearly did not understand the third column - I thought that had to do with the client. Our network engineers made the update and we're good now.
