expo build:android fails after adding splash screen


Hello folks,
when I add the expo splash screen I cant build an apk anymore with: expo build:android.

I added the splash screen like this in app.json:

“splash”: {
“image”: “./assets/splash.png”,
“backgroundColor”: “#8BC051”,
“resizeMode”: “cover”

This is the error:

Task :app:mergeProdKernelReleaseResources FAILED

I tried different .png files and exported them a couple of times to make sure they are converted correctly. I even changed the path of my assets to the standard path similar to the documentation. I also added the different “xxxhdpi assets” for android in “android”: {}, because I was seeing the warning. That also didn’t help.

expo build:ios works fine.
My sdk Version is 32.

Hope someone can help me.
