Error (10:10)

Hi 

I have installed the last version, which is 2022.003.20314 

This run on server 2012 R2 in a Citrix environment.

The users work on an app name  Chameleon. 

This is a web medical application that runs from Internet Explorer, 

from the app, they open PDF docs. 

now we are still getting this error of (10:10) even with the last version and this error can happend a few tims a day per use 

when this happens, the user needs to close the connection to Citrix and open it, as after you get this error, you can't open any pdf files

I have looked, and I can't find any working fix for this, so I need your help
