We needed to add proguard rule because of https://source.chromium.org/chromium/chromium/src/+/main:third_party/angle/third_party/android_deps/buildSrc/src/main/groovy/ChromiumDepGraph.groovy;l=39. and for some reason it seems to be affecting only android 8.

Both @vlad-hoff & @Uni-verse confirmed that the crash appears to be resolved once they ran through a quick spot check with builds that @deeppandya provided which had the above fix. Because the 1.58.x release is scheduled for tomorrow, we need to get the above into 1.58.x ASPA so we can respin. @vlad-hoff also added the following video via Slack demonstrating that Brave doesn't crash when using VPN on Android 8 as per the following:

Followed the STR from the issue. and it seems to be working as expected. it doesn't crash at all and i was also able to buy the subscription and start the vpn tunnel. Here i have attached the recording with 1.58.123 manual build .
