Opened a previous project after downloading Dolphin Canary 9.
Was asked to upgrade Gradle due to Minimum supported Gradle version is 7.4.2. Current version is 7.4.. I clicked Change Gradle version in Gradle wrapper to 7.4.2 and re-import project several times, but that did not seem to perform any action, as the message Minimum supported Gradle version is 7.4.2. Current version is 7.4. was still displayed. However then clicking "Open Gradle wrapper properties" the gradle.properties which was opened had had the version changed to 7.4.2. Pressing Try again to sync did not help, still the message about upgrading Gradle.
I then remembered switching JDK from the local one in /use/local/buildtools/java/jdk to Studio Embedded JDK (in /usr/local/google/home/sgjesse/android-stusio/2021.3.1.9/jre). Switching back to one in /use/local/buildtools/java/jdk fixed the issue and pressing Try again synced the project.

See attached screenshot of trying "Change Gradle version in Gradle wrapper to 7.4.2 and re-import project" several times.
