The CC 2019 or later should give you an option to sign out from an earlier device. See https://helpx.adobe.com/download-install/using/device-activation-limit.html. (I'm not sure if this behavior has changed in CC 2020; I'll need to check that)
Sign out from your Account page
- Sign in to your Adobe account
- Under My plans, click Manage plan.
- In the Activated devices section (toward the bottom of the page), deactivate the device.
