There is a known issue with certain older plugins causing a crash on place open. This is the only crash we are aware of at this time.
We are working on a fix for this but in the mean time you can either disable this Beta or turn off any plugins you think may be causing the crash. You do NOT need to reinstall Studio to resolve this.
I like that the new icons are color-coded for more accessibility. Reduced clutter is always welcome, too. But my brain will inevitably need a few days to associate the new buttons/layout with their functions. Muscle memory takes time to adjust.
Getting all of Studio moved over to the new styling is a much bigger project than you can imagine. But we do plan to do it once we have the styling more settled.
The biggest issue I have by far with this re-design is how much more space is taken for the same amount of info. I like the compactness of the current UI, and I don’t like having big rounded buttons that pop out.
Will minimized ribbons be possible?
Yes
Is there a timeline for ‘Test’ tab integration?
We are integrating various parts of the old Test tab into new areas of the UI. Multiplayer test will be in the upper left Play Test area. We just didn’t have the UI ready for it in time of this release but it will come out sooner than later.
With custom tabs you are welcome to build your own “Test” tab and put whatever tools/buttons you’d like on it. No ETA yet on custom toolbars but it’s a top priority for the team and we’re just getting started on it.
Thanks for the questions and suggestions!
Ok, that looks really good! It’s a mix of not being visually overwhelming like current studio, while being space efficient. Keeps the main design ideas of the new ui, while being compact.
Good to hear! I’m glad, Sounds exciting!
Step 1 is to get all of Studio using a single “background color” value and implement background coloring in the same way 
That will take a while, sadly. But I do think if we do this properly, themes and deep customization becomes highly possible.
Is a there a place I can find the source code to this ribbon (luau)?
One simple question if you mind, but are we able to make custom skins for Studio and put them on so we have custom UI we’d like to have?
Since the new UI is being built in Luau, I feel like we could end up seeing programs to mod the look of the UI completely. I know it would be much easier, but also still complex.
Not anytime soon. Things will be under heavy development for a while and then there’s some work to get it into “open source” shape (not just the code but the repo set up and workflow for reviewing PRs, etc.)
But a definite possibility in the future! 
Hosting studio UI under GitHub would be insane, and I would 100% be making some contributions there
Just want to be sure, each window (explorer, toolbox, properties) has their own team, right? And if that’s the case, will there be a separate announcement post when the teams update their windows? Or will you guys just update this thread?
Quick question Paul, I’m guessing the current menu bar that is in the beta release is only temporary, right? Since in the RDC announcement there was a completely different looking one
On a side note: it would be really nice to see these buttons moved into the title bar like VSC does it;
Edit * I found out how to disable the beta from the ‘new place’ screen when studio loads. So I am able to get into studio again, I still think maybe a warning might be nice.
Saw this message too late, and the reinstall didn’t help any.
So I would disable plugins, except I can’t open studio to disable them.
How can I disable the plugins outside of studio.
Also, maybe a heads up in the original post, saying this might happen, and give instructions on how to disable plugins
Thanks
Sorry to ruin your day but the positives are: this is just Day 1 of a Preview release and your feedback is consistent with a lot of other folks!
Many weeks of updates coming before this becomes the default and hopefully we’ll make every day better for you. 
they may keep the OG one up for like a year or two, but I can’t see them keeping it around forever. i’m pretty sure this new one is the direction Roblox wants to go in for Studio, plus I’ve heard that it uses more updated code than the old one.
having to work with 2 different versions of studio, adding features on both the OG and new one would be a nightmare for them. It’s a reason why most companies don’t give you the choice. (all those reasons, plus money!!)
