Hello, I am developing using jetpack uwb.

We confirmed that Ranging works normally using Multi Session.

However, I have confirmed that an error occurs when closing a Session.

I'll show you the error I'm getting with an example below.

Example1
1. prepareSession().collect in job1, prepareSession().collect in job2, job2.cancel, job1.cancel

This is the case of prepareSession().collect in order and then closing them in reverse order.

Result: job2 is closed success normally. However, if job1 try to close after job2 is closed, an error occurs.

Example2
2.  prepareSession().collect to job1, prepareSession().collect to job2, job1.cancel, job2.cancel

Again, after ranging Jobs in order, close job1 first.

Result: job1 is closed, but job2 suddenly terminates due to PeerDisconnect. This causes job1 to work normally without being terminated.

java.lang.IllegalArgumentException: PeerDisconnect Disconnect 40DA



I am canceling the corresponding job when ranging and closing through different jobs.

I've been trying to find these solutions, but no one knows. So, I'm asking because I think it might be a library error.
Please give me a solution for this.
