Lack of motivation and thus focus could be due to many factors. Finding the root cause is the first step.

If it is due lack of social contact (due to working from home), try hanging out with friends or acquaintances everyday. It's a good idea to do that anyways.

Lack of exercise and exposure to sunlight can be a factor. Being outside on a nice sunny morning really cheers me up. Carve out time to walk in a park or in the midst of nature.

If the work isn't interesting, try to see if there are other places you can contribute and ask for it. If you can also identify a interesting problem worth solving then you can own it and run with it.

Lack of appreciation at work or from colleagues can also be a factor. If that is the case, acknowledge that many are also going through a rough time at this point. Perhaps you can help set an example and try influencing the culture a little bit. For e.g. an attaboy on a solid PR to a colleague or engaging in conversations outside of work before start of meetings.
