Upgrade to 2017.4.17f1 - A lot of crashes on 7.0 - 7.1 devices

I have release the last version of my game (with new features) with the latest LTS version of 2017. I have upgrade from 2017.4.14f1 to 2017.4.17f1

I tryed to use the new Android bundle support , but since I need to add a proguard file or resolve the duplicated dependencys on the gradle system I just roll back to the APK system. ( I use L2CIPP system instead of mono)

I uploaded the apks ( two of them x86 and ARMV) and released to 20% of my game population,

After 2 hours, the block rate per 1000 install have up to 53,24 from something nearly 0. After some digging I have found that the ARMV APK is crashing with android 7.0 and android 7.1 with

I will try to go back to the 2017.4.14f1 version and try again.

Any ideas or help will be appreciate

 

After some searching, this is related to multi dex compilation, this seems to have some relation

Maybe the changes in the compilation system have introduce this bug?
