Problems with parallel executions

[Ricardo Martin]

Hi!

I am having a problem with queue in Selenium 4. My problem is that when I have queues ( more or less more than 5 executions) the driver tries to execute the proof, openning the windows but I can only see a blank windows with the name "data:" in the Google browser and, the execution does not work. 

I am using Chrome and I can reproduce the same scenario in Edge, the proofs work. when I don´t have queues , 

I am working with linux hub and 4 differents windows nodes.This problem began when I updated from Selenium 3 to Selenium 4. I am using 4.6.0 version and we are working on update this version but I would like to ask If you are detected this problem or If It could be configuration problem because in the chagelogs I cannot find answer. Do you know something about this?

Also, I am usign open jdk 11 and the logs are these ones :

java.lang.NullPointerException

You can see that is having a problem with screnshots because the executions doesn´t run.

Best regards
