kapt plugin throwing error with kotlinx.coroutines 1.7.x

How frequently does the bug occur?

Always

Description

I have updated my app dependencies and some now depend on org.jetbrains.kotlinx:kotlinx-coroutines-core:1.7.1 and org.jetbrains.kotlinx:kotlinx-coroutines-android:1.7.1. Before, they were version 1.6.4. When building the project now, Realm throws an error Field "xyz" of type "@org.jetbrains.annotations.Nullable byte[]" is not supported. Field xyz being a variable of a RealmObject implemented in Kotlin (var xyz: ByteArray? = null).

I tried updating both to the latest version (as of now 1.7.3) but the issue remains. When explicitly downgrading to version 1.6.4 it works again: implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.6.4!!") implementation("org.jetbrains.kotlinx:kotlinx-coroutines-android:1.6.4!!")

The release notes of kotlinx-coroutines 1.7.0 list some breaking changes, but I haven't been able to find more details.
