Closed work permit is expiring, PR is still in process

[Rex cao]

Hi everyone,
I am Rex.
My current situation is my work permit is expiring in a month, My PNP PR is still in process.
What can I do?
My PNP PR has been past 22 months now, but it is still stuck in background check which has been taken more than a year.
As my work permit is closed work permit, it has employer restriction, am I still able to apply bridge work permit?
If not, what should I do? If I have to stop working because of it, will it affect my PR process?
Any idea?
