Firefox Driver fails with org.openqa.selenium.SessionNotCreatedException:

I am getting this exception when running tests in Firefox.

Firefox version: 98.0.1
Selenide version: 6.3.4 (Selenium 4.1.2)

I was getting the same error running my tests using Selenium 4.3.0 and Firefox 91.6. I downloaded the latest geckodriver from here (0.31.0 at the time of this writing) and that resolved the issue for me.

Android Studio Emulator wont start

So everything was working fine, today I opened android studio and try to run the emulator, and it wont start. I will provide the errors in an image bellow.
I tried wiping the emulators data , and disabled the antivirus, I tried new device...
Please help I need it :(

Possible solutions
Invalidate/Restart Android studio
Open AVD Manager select you emulator and wipe Data from the dropdown
Installing Intel latest Intel HAXM
or delete current emulator and install new one

I want to say, that any possible solution did not work for me, I lost 4 hours working on that. I quit and installed Genymotion , I can tell that it runned smoother than the android emulator.

Getting error for selenium test execution with jenkins on QAT server, it's working fine with local jenkins

Currently, I am doing automation of a project and writing Tests thru selenium and java it's working fine when I am executing tests from
Jenkins on my local server but on QAT I am getting an error.Previously I have written selenium test and now I have started using Jenkins for build and integration with Git on my windows platform.
Also, chrome path I am using for QAT server is I have changed to
System.setProperty("webdriver.chrome.driver", "C:\Program Files
(x86)\Jenkins\jobs\SPOSAUTOMATION\workspace\Driver\chromedriver.exe");

org.openqa.selenium.WebDriverException:
Timed out waiting for driver server to start.
This is the log file generated after execution build test thru Jenkins on
QAT server of the application.Here chromedriver started execution but not getting connected with chrome server and throwing a timeout exception.
Please ask me if any further information required to resolve the issue.

Is your selenium server active on the machine you are trying to execute the code through Jenkins?
you can check that, and start the server on command line from the location where selenium standalone server is located. Try the following command(modify the paths) :
java -jar selenium-server-standalone-2.53.1.jar -Dwebdriver.chrome.driver=c:\path\to\chromedriver.exe

Which OS you are using on your http://192.168.10.91:8081/ (server)? If it is Ubuntu then try executing scripts in headless mode and follow these steps:
Download and enable Xvfb before the start of selenium script on Jenkins. For more info read here https://wiki.jenkins.io/display/JENKINS/Xvfb+Plugin
To be on safer side try to keep chromedriver in "usr/bin" folder.
Now run the script.
