I hate Scrum

Sorry for your bad experience, so far I've had a really good experience with scrum, it helped me a lot with managing my tasks because I had a knack for underestimating the complexity of tasks.

And if fixing it is not an alternative, you could then try to look for another place to work, make sure to bring up questions about their workflow during interviews, and make sure that they really understand how agile works. not doins scrum wrong, but still... I'll have to be that guy and emphasize: that's not a fault of scrum.
By the definition of scrum, the team should decide their tasks (a manager should never designate them), the pace should be sustainable (there are some critics about the phrasing of "sprints" giving the wrong idea. it's not a sprint, it's marathon), and story points should not be a measure of productivity but a way to estimate how much will be done in every sprint so the costs can be managed, and so POs and managers can choose and prioritize which features should be implemented first, and have some idea of how long it will take.
Now, don't take my word for it. I wouldn't.
But if you have the time I highly recommend reading "Clean Agile" from Robert Martin so you can see what agile is really meant to be, and maybe it will give you some ideas of what your team needs to change to fix these corruptions.

And if fixing it is not an alternative, you could then try to look for another place to work, and make sure to bring up questions about their workflow during interviews, and make sure that they really understand how agile works.
