Would it be a good idea to invest in stock whilst in covid?

That depends on your own personal situation. If youre working and have money to spare, I dont see why not. If you arent working and living off of what the govt can give you, no way.

Nope. YOu have to wait till it is over.

During a time of uncertainty like this the market can be quite volatile (i.e. big ups and downs).  It is high risk but also high reward.  So if you are a conservative investor that makes it tough but if you are going for the big risk and the big payday, now's the time.  But be careful.  Like any gambling, never bet more than you are willing to lose.
