When I boot up the laptop normally, it works fine. But if I restart it, it freezes on the boot screen showing the flashing kubuntu icon.

I have seen this message on: journalctl --since today.

watchdog: BUG: soft lockup - CPU#2 stuck for 26s! [kworker/2:1:98]

The message is pretty clear you have a CPU problem. Another message it is telling you is it appears to be a heat issue.

CPU cooling insufficient? ---> in the way to disaster?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
