Doing a cold boot (i.e., "Power Off" or "sudo poweroff" and then pressing the power button to turn it back on) will make it start working again. This bug is a regression caused by commit 5aec98913095 ("ALSA: hda/realtek - ALC236 headset MIC recording issue"). I've already worked with upstream to get a fix for this bug into the mainline kernel, which has since landed as commit 69ea4c9d02b7 ("ALSA: hda/realtek - remove 3k pull low procedure"), with commit 46cdff2369cb ("ALSA: hda/realtek - Remodified 3k pull low procedure") as a follow- up. To fix this bug, those two commits just need to be cherry-picked into Ubuntu's kernel.
