Caused by missing check if neverReleaseUsers indeed contains any data.

In qliksense_license.js around line 620

            // Check do-not-release user names
            for (const user of neverReleaseUsers) {
                if (license.user.userDirectory === user.userDir && license.user.userId === user.userId) {
                    doNotRelease = true;
                    doNotReleaseReason = 'User is in the neverRelease.user list';
                    break;
                }
            }

Should be

            // Check do-not-release user names if there are any
            if (neverReleaseUsers?.length > 0) {
              for (const user of neverReleaseUsers) {
                  if (license.user.userDirectory === user.userDir && license.user.userId === user.userId) {
                      doNotRelease = true;
                      doNotReleaseReason = 'User is in the neverRelease.user list';
                      break;
                  }
              }
            }

Also do similar change before accessing neverReleaseTags, neverReleaseCustomProperties and neverReleaseUserDirectories arrays.
