I found another workaround option.
Turn off the Contact Profile for HubSpot as GarthMJ (the Accepted Solution) stated. Now that you have the Grammarly bar back, you can grab that window, drag it to the left-hand side of your email, and dock it there. Turn the HubSpot Contact Profile back on. Grab the right side of the Grammarly bar and size it to the left (skinny); the HubSpot bar (window) should show if it isn’t visible. See the photo below.
The downside is that neither of them can be full-size simultaneously, as far as I have figured out or found. Adjust them both by adjusting the Grammarly bar. The HubSpot window doesn’t quite get to be full size, but it shows enough IMO. It shows a little more than it is in this photo.
