Describe the bug

These days, I tried to use Github Actions to build Flet app. And all run properly if I don't use flet-build-template.
But when I follow the #2868 to custom signature, it started to error (All Builds .../ #12 配置签名等):

FAILURE: Build failed with an exception.

* What went wrong:
Could not open cp_settings generic class cache for settings file '/tmp/flet_flutter_build_a3wDZNSPpJ/android/settings.gradle' (/home/runner/.gradle/caches/7.5/scripts/5bahl4yp5mw7lcn2efkltdtgf).

Next, I changed gradle version to 8.4 and 8.5 in gradle-wrapper.properties and tried again, but raise another error (#14 ffff):

After this, I changed Java to 18 and gradle to 7.5, and it can build sucessfully with custom sign. But when I install it to my Android 10 phone, Instead of showing the normal app interface, it keeps a white/black screen after the splash activity is displayed (depending on whether dark mode is enabled, worked fine in the last successful build apk, tested the project itself using the Android flet app and had no errors).

You can find this (maybe crashed) apk in #24 workflows, and this is direct link.

And it's "last successful build apk" in workflow #11: Link

In passing, I can't change my app name from "phiname" to "PhiName" (in PRODUCT_NAME env)
