This issue seems to be affecting multiple people (including me) even if we have a capable machine and I have tried both downgrading to 1.4 and literally just having mors longa and it's requirements but still the same issue occurs, so at this stage I suspect either a driver issue or an issue with teardown itself hence why I am suggesting you post your specs here as both the PC's I have this issue with have amd cpu's and one has NVIDIA gpu while the other an amd gpu, so please provide anything you find so we can try and solve this issue!

EDIT: Reseting the story progress seems to resolve this issue for some, but do note this will wipe ANY campaign progress in teardown.
