Hi,
I am in the same boat. But I am currently on a work permit too. Just before you get worried more - you can apply for a visitor visa as a family member of Canadian citizen if you don’t have any other temporary status. Write a strong letter of explanation as to why you want to be with your spouse and how the pandemic has delayed your pr processing.

Select to unite with a family member who is a Canadian citizen
This is a different portal which gets you visa in 30 days. I myself applied through it and mentioned that I have a work permit and pr file in processing + my spouse in Canadian. Received my visa in 20 days.
There are not many people like us who also recently got married while having a pr in processing so you might get answers that don’t help. My situation is slightly different than yours as im already in Canada and working but if you want to reunite with your spouse, your pr file shouldnt get rejected - ircc mentioned last year they are trying to prioritize families who haven’t seen each other for a long time due to the pandemic and expediting these visas. While I cannot guarantee approval - It is worth a try and won’t affect your PR file.
Also, make sure you notify IRCC about your marital status change through webform.
For your PR file please submit your record of solemnization, marriage certificate, letter explanation explaning how you got married, when you did,how you met and all that background - like a story plus also share your spouses documents that prove citizenship status (citizenship card and passport). You should do this as soon as possible to update your pr file.
Hope this answer helps!
