As a workaround, you can add the attachment’s OneDrive/Teams link in the “Notes” section of the task.

If I add a link to a file on my harddrive to the Notes section of a task, this link's color turns properly blue, if I hover over the pointer changes to a hand (which also seems correct) but clicking on it actually results in no action at all.
Could it be some security setting that prevens the file to open ?
We have the All, Assigned to you, Important, Completed and Planned smartlists.
Within the Planned smartlist you can have Today, Tomorrow, Weekly and Later subsections.
