From my own experience, it's just not a good time to change a job no matter how enticing it sounds.
The fact that everyone is remote is actually a great 'leveler', since the company has a 'main office' and a few satellite offices in other cities. I'm not affiliated with the 'main office', but I actually am concerned that I'll suffer career-wise once the company goes back to in-office, since I'll be in a satellite office missing out on casual-but-important lunch/coffee/hallway conversations.
So, from my perspective, it's a great time to change jobs. YMMV.
