Mali G52 - Failed to create reader for mali GPU # 0

Qing Xia

Streamline version: Version 8.0.0, Build 20220217_150925 windows 64-bit.

Device: Mali G52(Bifrost - r21p0)  on Android.

If any GPU perf counters are selected from "Add counters from a template", the capture will not start with:  

If I capture without any mali counters selected, I can successfully get a capture(with only CPU info).

    Thank you for your reply.

    I cannot find out how to upload the full log here. :( 

    I am posting what I think is relevant here:
