Here are my dependencies

implementation 'androidx.core:core-ktx:1.3.2'
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'com.google.android.material:material:1.3.0'
implementation "androidx.compose.ui:ui:1.0.0-beta06"
implementation "androidx.compose.material:material:1.0.0-beta06"
implementation "androidx.compose.ui:ui-tooling:1.0.0-beta06"
implementation 'androidx.lifecycle:lifecycle-runtime-ktx:2.3.1'
implementation 'androidx.activity:activity-compose:1.3.0-alpha08'
implementation "androidx.navigation:navigation-compose:2.4.0-alpha01"
testImplementation 'junit:junit:4.+'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
androidTestImplementation "androidx.compose.ui:ui-test-junit4:1.0.0-beta06"

Jetpack compose used to work fine for me on Artic Fox Canary but when I build my project on Artic Fox Beta 1, I get this error.

Getting the same error on latest Android Studio Bumblebee | 2021.1.1 Canary 1 — Adi, May 20 '21 at 09:59

Update all compose libraries to beta07:

implementation "androidx.compose.ui:ui:1.0.0-beta07"
implementation "androidx.compose.material:material:1.0.0-beta07"
implementation "androidx.compose.ui:ui-tooling:1.0.0-beta07"
androidTestImplementation "androidx.compose.ui:ui-test-junit4:1.0.0-beta07"

implementation "androidx.navigation:navigation-compose:2.4.0-alpha01"

It would be better to use something like:

ext {
    compose_version = '1.0.0-beta07'
}

and then:

implementation "androidx.compose.ui:ui:$compose_version"
implementation "androidx.compose.material:material:$compose_version"
//...

The issue exists with the compose compiler. It's not just enough to update compose libraries, the compiler needs to be updated to at least beta07 as well. This is easy to miss as it's not with the list of dependencies and doesn't have lint highlighting in Android Studio (yet).

composeOptions {
    kotlinCompilerExtensionVersion "1.0.0-rc01"
}
