Only at a concentration of 90% or higher and over a sustained period of time. 70% iso (the most common you find for sale) won’t hurt the backpack just cleaning off the sticker.
almost certainly both will damage print. something like lighter fluid (or hexane) won’t, but it should loosen glue. trying to dislodge sticker with a razor sometimes works even better
some people suggest vegetable oil, but then you’re left with oily fabric
Nail polish remover or even some isopropyl usually works, too. Both dissolve typical adhesives and cost significantly less.
They aren’t generally safe for plastics either.

Those would definitely dissolve the plastic backpack as well…

My experience with cheap ass prints like this is different, the ink runs like crazy if you’re not very careful with it.

It doesn’t look like the spot where the sticker is, is even fabric. Just straight plastic.
i’d still try hydrocarbon solvent first, because it’s least likely to damage it
