@srirambv can you try a version with chromium 128 to see if it crashes? Just do the step 5-6 should be sufficient. Mainly I want to make sure if chromium 129 bump causes this because the Nightly build on Android after merge didn't have this problem.

It doesn't crash when running on x86 emulator

AlexeyBarabash commented 4 days ago
I have tried arm32 apk from https://github.com/brave/brave-browser/releases/tag/v1.72.75 - it succeeded version result

I have tried arm64 apk from https://github.com/brave/brave-browser/releases/tag/v1.72.75 - it crashed version result
Image crash, no screenshot

It doesn't crash on local component arm64 build but it crashes on static arm64 local build
