When we tried to update Global Settings, we've got a crash and we found these stack in jenkins logs:

  Looks like the configuration got submitted without the priority strategy definition. Not sure what caused that...
  
  Could you please confirm that the Jenkins version is 2.249.3 and not the recent weekly?

  I confirm Jenkins version : 2.249.3.
  
  The error occurred right after installing the plugin. We were never able to change the settings.

  Can you provide the `jenkins.advancedqueue.PriorityConfiguration.xml` and `jenkins.advancedqueue.PrioritySorterConfiguration.xml` file content.
  
  It should be in your jenkins master home (JENKINS_HOME) directory.

  There is an error in the provided `jenkins.advancedqueue.PriorityConfiguration.xml` file. 
  
  ...
  <priorityStrategies>        
    <jenkins.advancedqueue.JobGroup_-PriorityStrategyHolder>          
      <id>0</id>        
  </jenkins.advancedqueue.JobGroup_-PriorityStrategyHolder>      
  </priorityStrategies>
  ...
  
  It should more look like this.
  
  <priorityStrategies>        
    <jenkins.advancedqueue.JobGroup_-PriorityStrategyHolder>          
      <id>0</id>          
      <priorityStrategy class="jenkins.advancedqueue.priority.strategy.UserIdCauseStrategy">            
        <priority>1</priority>          
      </priorityStrategy>
    </jenkins.advancedqueue.JobGroup_-PriorityStrategyHolder>
  </priorityStrategies>
  
  The property `priorityStrategy` is missing and this cause a NullPointerException at Runtime.
  If you would add the missing property the plugin should work as expected.
