I get Activation of Connection Failed - after restarting

I found dozens of these questions but they either didn't work or were way too specific for the user.

I have Lenovo Thinkpad E15 and freshly installed Ubuntu 20.04. First, it didn't find any wireless adapter but after researching a bit I installed the rtw89 driver and it worked, well halfway at least.

My home network connects but after rebooting it doesn't and gives "Activation of Connection failed.". I can connect to my mobile hotspot, but as I said not to my home network. After reboot and getting this error, when some time passes it connects again and I'm happy until my next reboot...

People at same questions seem to ask a command's output so I will add it too. sudo lshw -C network's output:

Look at the logs! `sudo journalctl -b 0 -u NetworkManager`. Read `man journalctl`.

Maybe not the best solution but I can use my WiFi, problem free after freshly installing Ubuntu 20.04 MATE. It uses 5.4 kernel opposite to Ubuntu 20.04's 5.8. I'm not sure if it was a kernel issue but it's gone with MATE.

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.
