[keremcadirci]

What version of Janus is this happening on? Janus version: 1202 (1.2.2) Janus commit: a0175e89735bacfee4e5bc2185ec2e05f02a7358

Have you tested a more recent version of Janus too? No

Was this working before? I don't know

Is there a gdb or libasan trace of the issue? Please find full log at https://gist.github.com/keremcadirci/f4ea619dcc458f80c299182665258b92
