I believe the issue with straws is they were hard to recycle because they were lightweight and often mingled with other materials, such as cups, napkins, and food waste.

They were generally made from PP which is widely recycled as a material.

They are also commonly littered and as they don't break down in the environment led the not only being unsightly but also clogging up waterways and direct damage to wildlife. Paper straws can still be littered, but break down so don't cause the same physical problems in the longer term.
