That build log states, specifically: ```auto * What went wrong: Execution failed for task ':app:validateSigningRelease'. > Keystore file F:\Fuse-Workspace\salehapp\release.keystore not found for signing config 'release'. ``` Please check if you have put the `release.keystore` file where it is expected to be. You should have generated it by following [the signing instructions](https://www.fusetools.com/docs/preview-and-export/signing). ---
