Company going through re-org post merger and layoffs. The new department assigned is really uninteresting and less work.

While, I am grateful for not being laid off, the atmosphere at the company is super depressing and feel like my growth is going to stunt here. I'm unsure whether I should let this phase pass or move on and look for something better. In terms of work, it doesn't seem the needle is going to move much in the next year. Growth and learning is really stunted. Not sure what to pursue.
