If she can get the window glass back up into position, duct tape it into closed position, do not use window until blocks replaced. The glide blocks are inexpensive. Regulators which lift and lower the glass much more expensive. Don't bend the regulator with further use.

If it is a broken window guide, she will notice that the glass is slightly crooked and not level with the top of the door body. Also a lot of rattling when closing the door. If she cannot get a good grip on the exposed glass to try to pull upwards, she may have to take the door panel off.

Easiest is to try a new switch, I hope yours is in the mail already.

Keeping it running is better than buying new

Since there's a good chance a window "glider" has broken (thus jamming the window) I suggest she should at least try holding the glass with strong tongs (silicone kitchenware perhaps) and pulling up whilst holding the switch in the up position. Give it some shake-action.
Has she tried that?
