App not installed after adding plugins in Unity

After adding the AVPro plugin in the Vuforia project in Unity I receive failure on install:

Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES: Failed to collect certificates from /data/app/vmdl1893700733.tmp/base.apk using APK Signature Scheme v2: SHA-256 digest of contents did not verify]

It was installed once after increasing the app and bundle versions. But the next builds have the same issue. Does anyone have an idea how to solve this problem?
