For Kotlin 2.0 and KSP 2.0 the Cannot change attributes of configuration ':composeApp:debugFrameworkIosX64' after it has been locked for mutation
really seems like a KSP issue. You should file a bug in their repository with a sample app if possible.
If you downgrade to Kotlin 1.9 then things 'should' work, there are example apps out there with such configuration, like the following one:
ap...@google.com <ap...@google.com> #3
Will try to use the example provided by you to check if it fixes the issue.

Note that this issue happens when applying the Compose, KSP and Room Plugin together in Kotlin 2.0.x, the workaround for now is to not use the Room Gradle Plugin and instead specify the schema location vis KSP arguments:
// In the build.gradle
ksp {
arg("room.schemaLocation", "${projectDir}/schemas")
}

Hi, I encountered a similar problem and was able to resolve it by updating the dependencies
room = "2.7.0-alpha08"
ksp = "2.0.20-1.0.25"
compose-plugin = "1.6.11"
kotlin = "2.0.20"
Description
Version used: 2.2.0
Devices/Android versions reproduced on:
- device usb:336662528X product:xcover4ltexx model:SM_G390F device:xcover4lte transport_id:5
- device product:sdk_gphone_x86 model:Android_SDK_built_for_x86 device:generic_x86 transport_id:4
- device usb:336662528X product:zerofltexx model:SM_G920F device:zeroflte transport_id:15
In Version 2.1.0 annotation @Relation was only allowed for list types, if you used it on a non-list type the following runtime error occured:
error: Fields annotated with @Relation must be a List or Set.
Since Version 2.2.0 @Relation can be used on non-list types, in order to model relations with a single object reference.
This is handy if you have 1-to-1 relations and you don't have to explicitly get the first item from the result list, instead you get the object directly.
release notes:
One-to-One Relations: The restriction in POJO fields annotated with @Relation to be of type List or Set has been lifted, effectively allowing single-value relations to be represented.
It seems that this new feature is only supported up to a certain amount of table rows. In more details it means that if you run a query on tables with 100 rows, the returned POJOs have all valid non-null references to the object specified by the @Relation annotation. If you run the same query on tables with more than 999 rows (999 still works, 1000 will fail) the result will be that all returned POJOs have NULL as referenced object (see my example project).
If you use the list type with @Relation annotation you don't have this limitation.
Please refer to the attached example project unit test.
In the example project the same entities are used but with two different POJO types. One is using a List<> type annotated with @Relation, and the other is using the newly supported object type.
Android unit test show that the list type always works but the object type works up to 999 rows, after that it starts to fail.
