Thank you. Setting the subtheme.libraries.yml described in #3 and disabling the bootstrap_library module fixed the dropdown issue for me. It also fixed the issue where the components/node "hide node label" checkbox had stopped working. This all worked when using the base theme but had issues when I moved to the subtheme but all good now.

Update!
If you update Bootstrap Barrio module to the most recent version, then drop-down menus in the subtheme may not work again. Check the bootstrap_barrio.libraries.yml file to find out which version of CDN the module is using, then copy that version to the subtheme.libraries.yml file as described in #3. With the newest Bootstrap Barrio version as of now, the version is 5.2.0, not 5.0.2, as it was previously.
