Whether or not its Ubuntu or Lubuntu I don’t see as really matters; however as Lubuntu 22.04 LTS is EOL, it’s off-topic.
If you read Welcome To Support And Help you’ll note flavor support is specifically mentioned; as its three years for a LTS, as only Ubuntu Desktop, Ubuntu Server and specific products were extended from 3 years to 5 years for LTS.
Ubuntu 22.04 LTS, which is the base OS used by all Ubuntu flavors, is still a supported system, which was why I made my prior suggestion.
If the question is about Ubuntu 22.04 LTS with LXQt, to me the question can be treated as being on-topic here (and other support sites too), but if it’s about Lubuntu 22.04 LTS then as that release is EOL, it’s off-topic on numerous sites including this one.
My comment could be seen as a hint, rather than me trying to act as a moderator and start closing a question as off-topic.
