Dreamweaver 21.5 unstable & crashing [MERGED by moderator]

Dreamweaver won't stay open on any PC longer than 30min. It crashes while idle.

It's been 7 days since I last reported updating to Dreamweaver 21.6, and happy to say after using it daily, it hasn't crashed and is working perfectly.  I'm using a PC with Windows 11.

ALWAYS crashes. What other app crashes in 2025 and loses your work? Primiere is arguably far mroe complex app and never freezes and crashes. I believe years ago they did a poor rewrite for PC that is still used. FYI, I also use on the Mac, which does not crash.

Yesterday, I updated Dreamweaver to the latest version (21.6). I hadn't had a chance to downgrade to 21.4, which was the last stable version, but so far 21.6 has not crashed.

Today, I tested some common actions that previously triggered crashes, specifically copy and paste and everything is working smoothly so far.

I'll continue to monitor Dreamweaver over the next few days, as I use it daily for work, and will provide another update soon.

This morning I ran the Creative Cloud Desktop software, and there was a new update for Dreamweaver, 21.6. "This update includes bug fixes and stabiltiy improvements." So far, so good.

just wasa forced to imnstall the new DW - what a piece of CRAP- I can't see the page poperties - and the program keeps crashing.. I am paying for this garbage  HELP me fix this 

I have Dreamweaver v21.5 Build 15662 on Mac and for quite some months now it just hangs and goes completely unresponsive at different times during the day.

All I can do is Force Quit it in the Mac Finder and restart and I lose unsaved work.  It can happen almost hourly, sometimes more frequently.  Very frustrating.

No updates are available in Creative Cloud.

Any ideas?

This past week, I just purchased a refurbed MacBook Pro, with M4 Max chip, and operating Sequoia 15.6.1. I'd only been learning to use this updated Dreamweaver platform for the last couple days, having been using a 17" Macbook Pro (2011) for as long as I could before 'planned obsolescence' made work on it too difficult. I was effectively using Dreamweaver on that years old. Last night, there was a software update...and Illustrator and Photoshop are still operating, but Dreamweaver crashes on opening. Restarting and going through 'Library' options offered on the platform...nothing gained. Crashes repeatedly...never actually opening to operate for a moment. Totally...bizarre...with the other CC products still working? Anyone else seeing this? 

Yes my DW also crash on my Windows 11 pro, but I let it do it because if I have not lose any work I have not saved, then you restart DW if you not have saved it will recover to that point there it crashed, it's only to save the first thing you do and continue to work. I know it is annoying to do, but it does not matter for me,  because I haven't any time press as maybe some of you. I have still not found any desktop app that can replace DW, yes there are many browser apps how can i not interest of them.

@Nayan_Kankariya earlier this morning I replied back to someone else mentioning Dreamweaver freezing up just like when they said Adobe Illustrator would freeze when using the keyboard command "ctrl+C" and "ctrl+V" and I mentioned that I noticed the same issue when using that command on my PC.  Just now while I was in Dreamweaver I used that command and immediatley after I did a "ctrl+V", Dreamweaver freezed and crashed just like it always has

I'm about 90% sure the cause of this freeze/crash issue with Dreamweaver 21.5 for 4+ months now is partially due to when using they keyboard "ctrl+C" and "ctrl+V".  Please share this to with IT Support team as this may also help resolve the problem.  Thank you!
