You've got a whole bunch of red flags, from being banned because you probably misrepresented (don't blame your agent - you were very much involved and had to sign off on everything before it was sent off) to now your wife spending too much time outside of Canada to where she is probably not eligible to sponsor you anymore. Good luck to you, I would expect a lot of scrutiny and for the sponsorship to take longer than normal.
They will be lucky if they get approved, they should be denied alone from the fact that the wife has been out of Canada for months now.
The problem is that if your wife left in March - she knew about coronavirus. There have also been multiple repatriation flights out of India. She had many chances to go back or even not leave the country at all (since that is what sponsors are supposed to do in the first place). I understand the situation in India, but you cannot continue blaming everyone else for the situation that you have both put yourselves into. If I can see that, then the immigration officer looking at your application will see it.
