Illustrator 2025 keeps crashing and won't open!

I've been having this problem recently too. What I found (cross your fingers that this was the issue) by searching is that sometimes your prefrences (workspace) is in conflict, so It can't load up properly. What I did, was (after trying to launch it repeatedy and getting one goos launch). Before you open any document go up to the Workspace area and go to "manage workspace" delete all of them, then make a new workspace. This seemed to allow it to load and open files. I just found this fix today.....so we will see. Previous "fixes" that did not work for me: 1. uninstall and reinstall illustrator. 2. uninstall and reinstall Creative Cloud. 3. adjust Memory settings. 4. try to roll back to an earlier version - this worked temporarily, but when I uninstalled, I lost the earlier version. Hope this new fix holds, and hope you can get yours working again. It's such BS when the newest version is worse to work with than the older one.

Hola Preeta_4266, me pasa lo mismo y todavia sigo trabajando con illustrator 2019 por que me pasa lo mismo que a vos, pudiste hacer algun cambio?

You can install previous builds of Illustrator using the Creative Cloud desktop app. Click on the Apps tab. In the table of apps under "Essential in your plan" you should see a tile for Adobe Illustrator. Click on the three dots icon in the lower left corner of the tile. That will show a flyout menu with options. One of those options is "Other Versions." Choose that and it will show several previous builds of Illustrator.

Regarding the crashes, there can be other factors causing them. Make sure the driver for your computer's graphics card or integrated graphics chip is updated. Any periphreals, such as graphics tablets, can also cause Illustrator to crash if their drivers are faulty. Certain applications running in the background at the same time can also cause issues.

@preeta_4266  may I asked if you did a clean un-install of Adobe Illustrator did you use Adobe Cleaner, https://helpx.adobe.com/ca/creative-cloud/kb/cc-cleaner-tool-installation-problems.html — this may help to remove cleaning corrupt installation files.

Once that is done, go back and log-in to adobe.com, or better yet, og into the Desktop Creative Cloud, which will show you other versions. As you can see, I am updating my Illustrator!  

Hopefully, that works for you!
