You can try to upgrade the package to latest.
If it does not solve your issue, you can use the legacy recorder as a workaround (also from latest version).

I tested the latest version, and the same error still occurred, but the issue was resolved using the legacy recorder.

OK so can you send me the stack trace de-obfuscated?
There's definitely something to fix for older devices/apis

ofcourse, this is full stack trace:
