Thanks for the report!
Could you please confirm for us which version of Compose is your project using? Does it happen if you change the version?

[Deleted User] <[Deleted User]>
I was using Compose 1.2.0-rc03 and Compose Compiler 1.2.0. But this issue was present in previous versions (1.2.0-RCxx) of the compiler too.
Yesterday I was testing how it works with Compose 1.1.1 and Compose 1.3.0-alpha01. It seemed to be working better, I could inspect the app for 5-10 minutes until it crashed. However, fetching view atributes was really unreliable: sometimes instantaneous, other times with a huge delay or not it all. And I believe crashes are related to the attributes section.
Most of the crashes had these messages in the Logcat afterwards: (see the attached file)
Description
Version used: alpha09
Devices/Android versions reproduced on:
When using WorkContinuation.combine to join multiple works before continuing, it has a check in it to make sure it's acutally combining multiple WorkContinuations. I think this check is uneccessary and annoying, and adds a hard to find bug in implementations. The combine() method could easily just do nothing if there's only a single WorkContinuation passed to it.
Current use case:
I'm uploading a number of photos, which I'm splitting into a number of WorkContinuation lists so that several happen in parallel. If I only have one photo to upload then obviously I can only split this into one list of work, and the app crashes because WorkContinuation.combine() 'cannot' combine a single item. To fix this I have to have this code:
```
val allCombined = if (workLists.size == 1) workLists[0] else WorkContinuation.combine(workLists)
allCombined.then(....
```
which is much less nice than the original code which I think should work:
```
WorkContinuation.combine(workLists)
.then(....
```
