Gardle sync error due to dependency being unresolvable - android-studio

Question

I am currently developing an android app with AR features using the library com.gorisse.thomas.sceneform:sceneform:1.21.0. It was working fine up until now. Whenever I try to sync the project the dependency is not resolvable.
I once had this exact same problem, but a simple computer restart resolved the issue. Now that doesn't work anymore. I tried deleting the .idea and .gradle folders and importing the project instead of opening it.
More details:
The error I get:
Failed to resolve: com.gorisse.thomas.sceneform:sceneform:1.21.0

What my build.gradle looks like:
plugins {
id 'com.android.application'
id 'org.jetbrains.kotlin.android'
}
android {
compileSdk 33
packagingOptions {
resources {
pickFirsts += ['META-INF/DEPENDENCIES']
}
}
buildFeatures {
viewBinding true
}
defaultConfig {
applicationId "com.example.rocksterapp"
minSdk 29
targetSdk 33
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
androidResources {
noCompress 'filamat', 'ktx'
}
namespace 'com.example.<appname>'
}
dependencies {
implementation 'com.google.android.filament:filamat-android:1.21.1'
implementation 'com.gorisse.thomas.sceneform:sceneform:1.21.0'
implementation 'androidx.fragment:fragment-ktx:1.5.3'
implementation 'androidx.appcompat:appcompat:1.5.1'
implementation 'com.google.android.material:material:1.6.1'
implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
implementation 'androidx.navigation:navigation-ui:2.5.2'
implementation 'androidx.navigation:navigation-fragment:2.5.2'
testImplementation 'junit:junit:4.13.2'
androidTestImplementation 'androidx.test.ext:junit:1.1.3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}
Edit:
I created a new project and just simply copied every file from the old one into it. Problem isn't fixed. Now not only one dependency can't be resolved but three. Sceneform is not included in these.
