Apple recalls beta versions of iOS 18.4 and watchOS 11.4 due to technical failure

Apple has unexpectedly withdrawn the watchOS 11.4 beta for all Apple Watch Series 6 models. This means that users can no longer test the new version.
Here's What We Know
This was reported by Aaron Perris on Twitter. In addition, the beta versions of iOS and iPadOS 18.4 have been withdrawn for some iPhone and iPad models.
A new beta version of watchOS 11.4 was released on 22 February, along with iOS 18.4, visionOS 2.4, and others. Although previous beta versions contained many new features, it is not yet known what has changed in watchOS 11.4. Two users on Reddit in the r/watchOSbeta section reported that their Apple Watch stopped working after installing the update. One of them said that they were using a Series 6, while the other did not specify. As a result, Apple seems to have decided to withdraw the new beta.
watchOS 11.4 beta 1 has been unsigned for the following devices:

In addition, Apple has withdrawn iOS 18.4 beta 1 for many iOS devices, including most iPhone 12 models, some iPad models released in 2020, and the cellular versions of the latest iPad Air models. Users have reported issues with rebooting their devices. Here's the full list of recalled models:

We hope that Apple will quickly release new beta versions. Interestingly, most of the affected devices were released in 2020.
