Wifi frequently disconnected when using bluetooth audio on Ubuntu 22.04

Since upgrading my DELL XPS 15 9570 from Ubuntu 18.04 to 22.04 (I also upgraded to 20.04 shortly but just to upgrade to 22.04), the Wi-Fi connection has been really terrible: It disconnects after reconnecting for just a couple of minutes (sometimes even less) and this happens very frequently. I have been searching for solutions for a while, and have tried a lot of things such as

Upgrading the kernel (my current kernel is 6.3.2 stable), or
changing the Wi-Fi power saving mode, but none of them really worked.

Recently, I figured out that ONLY when my laptop does not connect to anything via BLUETOOTH, the Wi-Fi is stable. When Bluetooth connection is used, Wi-Fi frequently disconnects again. I'm not sure why this is the case, as this didn't happen back then with Ubuntu 18.04.

I'm posting to look for a permanent solution where I can connect Wi-Fi and Bluetooth simultaneously.

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.
