Hello,
My attempt to reproduce this behavior was not successful.
Please clarify if there are any particular steps that are required to reproduce this behavior.
If this behavior appears only on certain machines, specify their configuration.
Also, send us the callstack of the exception.
We would appreciate you providing us with a small project to show this issue.
I hope to hear from you soon.
what exceptions I need to mark to show you all the necessary information?
Hello Maxim,
To get the call stack, you can use an approach suggested in the How to obtain the exception's call stack KB article. Also, it would be great if you provide us with a small compilable project so that we can research it on our side.
I am looking forward to your response.
