Updating plugins "Composer was unable to install the updates due to a dependency conflict"

I'm trying to update two plugins (Super Table and Navigation) in the CP and getting a dependency conflict:

Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting
see for more details.
- It's a private package and you forgot to add a custom repository to find it

Read for further common problems.
Running update with --no-dev does not mean require-dev is ignored, it just means the packages will not be installed. If dev requirements are blocking the update you have to resolve those problems.

I wasn't sure if it's something with Verbb plugins specifically or something on our end.

Steps to reproduce

1. Try to update from Navigation 1.1.13 -> 1.27 or
2. Try to update from Super Table 2.3.0 -> 2.3.3

I just tried running composer update on the exact same composer.json file, and everything installed without a hitch. Can you try running composer clear-caches and then try again?

Huh, that seems to have done it. Thanks!
