We have found this problem in our internal test recently and it is caused by a change of variable lifetime in XCode 11.4. Some pointers is released prematurely and causes memory access problems.
We have fixed it and it will be included in a recent 4.1.0 release.
Unfortunately, 2.0 is not supported anymore. As a workaround, you can use XCode 11.3 and consider upgrade to 4.1.0 when it is out.
