Could not resolve "@popperjs/core"

[ArmandRedgate]

Steps to reproduce

Link to live example: (required)

Steps:

1. Set up a new MUI project with the official instructions, specifically with version 5.16.2 (older versions are fine)
2. Use a Tooltip

Current behavior

Since the update to v5.16.2, I get errors like:

Could not resolve "@popperjs/core"

in vite and

Error: Cannot find module '@popperjs/core'
Require stack:
- /root/project/web-client/node_modules/@mui/material/node/Popper/BasePopper.js
- /root/project/web-client/node_modules/@mui/material/node/Popper/Popper.js

- /root/project/web-client/node_modules/@mui/material/node/Tooltip/index.js
 ❯ Object.<anonymous> node_modules/@mui/material/node/Popper/BasePopper.js:13:13

in tests.

This may be related to #42917. I should note that my package.json does not include @mui/base.

Expected behavior

No (new) errors

Context
