bug: crash on deinit() - Githubissues

Description

Calling init() and immediately after deinit() causes a random crash on some Android versions.

Steps To Reproduce

Run something similar to this:

for (var i = 0; i < 100; i++) {
await SoLoud.instance.init();
SoLoud.instance.deinit();
}

expect a crash
