You could consider downloading the matching Recovery package, https://images.ecloud.global/dev/bramble/recovery-IMG-e-2.2-t-20240717417775-dev-bramble.zip, and consider using this suggested method Installer stops after downloading, no error or acknowledgement just a "Try again" button - #7 by lma.
Easy Installer is undergoing reconstruction to a web-based version.
I would think it more productive to learn to do a manual install, Install /e/OS on a Google Pixel 4a 5G - “bramble”, than to debug this issue.
You might consider mentioning the failure in Feedback for v2.2
