Not seeing the install plugin button on plugin store available page,

      I checked 4 instances of Jenkins V2.260, V LTS, 2.240 etc

       

      When I am hitting available plugins page I am seeing the below error

      2020-10-06 16:35:37.344+0000 [id=13] WARNING h.i.i.InstallUncaughtExceptionHandler#handleException,2020-10-06 16:35:37.344+0000 [id=13] WARNING h.i.i.InstallUncaughtExceptionHandler#handleException,org.apache.commons.jelly.JellyTagException: jar:file:/var/jenkins_home/war/WEB-INF/lib/jenkins-core-2.260.jar!/lib/layout/isAdmin.jelly:28:21: <d:invokeBody> java.lang.StackOverflowError,

      Update Site link: https://updates.jenkins.io/current/update-center.json and https://updates.jenkins.io/update-center.json (Tried both)

       

      Tried spinning up a new VM and started Jenkins and seeing the same issue.

       

      I have not tried downloading the plugin offline and installing it, I know this will be an alternative.

          [JENKINS-63873] Unable to install plugins

          I have the same issue. Tested on 2.249.1 LTS and 2.259 Weekly versions and on Java 8 and Java 11. The result is the same on a clean installation of Jenkins. Also tried to install recommended plugins and do not install any plugins. The issue present in both cases. My system Amazon Linux 2 (CentOS).
