When/if cancelling a Render, Stager canvas goes black and I have to "force quit" the application...

Hey there. Soooo.. Quite frustrating so far trying to migrate from Dimension to Stager for me. If I cancel any render when I return to the stage it's black and I can't use or adjust the program anymore at all, I can't even "save" the project or even just quit the application. I then must bring up the "Force Quit Application" and force quit to close it, losing any unsaved changes. (I'm on a 2019 MacBook Pro with OS Big Sur).

There's another annoying bug I won't get too deeply into regarding black bars on models that are laying flat that never happens in dimension with the same models, forcing me to go back and use dimension again for odd projects.

While I'm complaining... being forced to take on the entire 3D suite cost (on top of my All Apps and stock subscription) seems a little crazy. Am I right in assuming Dimension will eventually be phased out since it's extremely similar? I personally believe this new 3D collection SHOULD be rolled into the All Apps subscription. It is after all called "ALL apps". We don't all work for larger agencies, I'm just an independent contractor trying to stay in business. Hopefully, Adobe will sort out their pricing/bundle tiers to give us more options that are realistic. I need about a half dozen of the All Apps programs and a couple of the 3D programs but not all of either. I'm starting to feel like I'm paying a second rent to Adobe.

Anyway, sorry for that rant. Photoshop, Illustrator and After Effects are incredible. They have literally been the most valuable and powerful tools in my workflow for over a decade. I don't know what I'd have ever done without them. TUT the costs just to move to a couple of 3D programs in addition while there are such bugs?.. yeah... like I said, I love ya Adobe, but it's getting a little crazy. lol
