Following the Cortex XDR Windows agent update to 8.3.0.49434 we started to see the following error affecting some application DLLs.
Clicking Ok makes the message go away and the application keeps working. TAC case was logged and an temporary Support Exception was added and applied to some affected hosts. This seemed to stop the error.
Wondering if anyone else is experiencing the same or similar issue? This affects approx. 2 DLLs on two separate applications of ours. I'd like to see a fix come in the form of an update to the Cortex XDR client, as applying a temporary support exception doesn't seem like a viable long term solution.

The thing only I know is that 8.4 is planning to be released on the week of April 15.
Even I don't know about 8.3.1, I guess it was planning to be released in late March and slide to behind in some reason.

This is more likely not going to be addressed in any future releases of Cortex XDR agent, given the fact that it's considered a feature that's been recently added in 8.3.0 and not a bug. Going the exception route targeting only those affected systems seems to be the way to get around this issue. You can either contact the vendor of the affected application and see if their software has a way to add exceptions for Cortex .exe process, otherwise you need to create an exception and target those affected systems only.

@Jurriaan So far in my testing with 8.4.0 I am not seeing the error reoccur with Teamviewer.

For me, 8.4.0 is not available yet....

Where do you see 8.4.0 released? I only know about creating the install inside the console and 8.4.0 isn't available, only 8.3.0.

Same here: in Cortex XDR Console only 8.3.0 available.

This morning I've received an email that maintenance release 8.3.1 will be available April 30th.
The release notes 8.3.1 state that the problem is addressed: "Fixed a compatibility issue with 3-party applications and Cytray.exe".
