Use gparted and create a new FAT32 partition with boot,esp flags. The run Boot-Repair to totally reinstall grub, default may not be that, and then you have to use Boot-Repair's advanced mode. https://help.ubuntu.com/community/Boot-Repair & https://sourceforge.net/p/boot-repair/home/Home/ Gparted is on Ubuntu live installer or can be downloaded as its own live system. https://gparted.org/faq.php

You need to use UEFI boot key on system to boot Ubuntu live installer. Unless you manually select the USB flash drive, it will default boot or try to boot from missing ESP.

So I would have to reinstall Ubuntu with a flash drive?

You don't have to re-install it. You need to boot from a LiveUSB and fix it.

Boot from an Ubuntu live USB, select Try Ubuntu, and use the built-in GParted partition editor to create a new 500MB EFI System partition formatted as FAT32 at the start of the disk manually. Then run the Ubuntu installer again. If the Ubuntu installation is successful, the Ubuntu installer will run all the way through the installation including installing the grub bootloader.

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.
