mbae.dll crashes Opera browser (again)

Hi

Since around August 18th we've been seeing crash reports with mbae.dll on stack. This looks similar to what's been reported here:

All reports are from Windows 8.1 or 10. Here's an example stack we see:

Since Opera is based on Chromium, the root cause may be similar to

Hello Mpawlowski,

 

Do you mind collecting the logs mentioned in this posts:

 

https://forums.malwarebytes.org/topic/144403-readme-first-posts-here-need-to-include-mbae-logs/

The logs have a log we can look into for more information so reproduce the issue and then collect the logs so we can look into that.
