Hello @Joy 

I would recommend removing IFS log files from his computer and restart application. See if still error exist. If so then create a support ticket.

1. Log out from application
2. Go to folder -→ C:\Users\{User NAme}\AppData\Local\Apps
3. You will find here a folder name 2.0
4. Remove the folder completely. This may take some time to complete.
5. Log in application

This will remove all logs and downloads from application. User will download all dll one more time.

Hope this helps

We have had similar issues with APPS 10 UPD16.

it seems to creep up randomly. 

here is the full error stack.

Really would love to see a permanent solution for this. 

Any help is appreciated. 

Thank you both for your replies. 

I’ve tried clearing the .dll cache in the past when users have had this issue, or similar issues - and it is never a permanent solution. 

Is there any other recommendation? Or is clearing the .dll cache intermittently or when the error occurs the only fix?

We are about to go to UPD 22 in the upcoming weeks. Is there a release that is better able to regulate these errors?

Thanks,

Joy
