Kaspersky 11.09 crashing when uploading PDF file on a software, but 11.07 does'nt. Logs show nothing.

Hello there!

I have a app called AllIms which uploads PDF files inside it (It is made using .net or similar), but everytime I upload any PDF on it, Kaspersky simply crashes.
I enabled all log options, on configuration options, but when the crash happens no logs are generated.

Only log I get is "Previous task was not completed." with a yellow warning icon.

The weird thing is that this is only happening on version 11.09.0.

If I downgrade tro 11.07.0, the app works fine.
I did not test 11.08.0.

Well, what could I do?

I tried troubleshooting this, disabled some modules, but still no success to understand what is happening.

Thanks in advance!

Can you try KES 11.11 and see if the problem still happens, please ?
