SplunkUI | app list error | V9.1.0.1 | (SVA S1 lab instance)

[NullZero]

I've just upgraded to Splunk v9.1.0.1 in a stand-alone (S1 SVA) lab instance from 9.0.x. All fine and operating at a basic level, see attached image. However since the upgrade there is a UI issue.

Unable to load app list. Refresh the page to try again.

I have checked splunkd error log and I'm not seeing anything notable:

index="_internal" source="/opt/splunk/var/log/splunk/splunkd.log" log_level IN (ERROR, WARN) 
| table event_message
| dedup event_message

 I have also verified consistency of ownership of $SPLUNK_HOME:

sudo find /opt/splunk -printf '%u:%g\n' | sort -t: -u  

 I'm not seeing anything obvious and I have checked the Known Issues list. Has anybody else seen this before I expend a lot of effort on a new release. I should mention that this is now using a Free 500MB license, I have a 10GB NFR license waiting to renew but I don't see this as an issue and it is not in violation.

Is there a solution for free licenses?

Hey @jwilczek I'm afraid not. Have you tried to run a later version of Splunk, I suspect you won't run into the problem there.

Update:

After installing an NFR licence and restarting Splunkd all the errors disappeared on the page. Therefore it is either licence 'feature' or error when a free licence is applied. @takitakitanana thanks for contributing on this.
