I have been working remote for the past 5 years because of covid but now my work wants me to return to the office. They have said that a failure to return to work in the office for partial weeks and eventually full time will be considered just cause for termination and I will get zero severance. Should I be getting severance and they are just trying to scare me off?

Your employer can require you to return to the office after working from home only if they provide you with proper advance notice. In some cases advance notice could be quite lengthy, depending on many relevant factors including your length of service, the commute time, etc. It's not clear from your description when the employer has announced the change and how clearly it has communicated it to you.
