The PARM error is often an indicator that Illustrator has reached a limit in its processing capabilities or encountered a file-level corruption. Common scenarios include:
Image Tracing: Using the Image Trace tool on extremely high-resolution or complex images can trigger the error if the resulting vector data is too heavy for the system to handle.
Corrupted Preferences: Over time, Illustrator's preference files can become damaged, leading to instability when accessing menus or saving files.
Memory and Scripting: The error may occur when a script or a complex operation (like resizing large text boxes) tries to access more memory than is currently allocated to the software's scripting layer.
External Factors: Operating system constraints, such as drive health or Windows' 260-character filepath limit, can also cause saving operations to fail with this generic code. Strategies for Resolution

Keyboard Shortcut: Close Illustrator, then relaunch it while immediately holding Cmd+Option+Shift (Mac) or Ctrl+Alt+Shift (Windows).
Manual Method (Windows): Navigate to C:\Users\[User]\AppData\Roaming\Adobe\Adobe Illustrator [version]\Settings and rename the folder to something like Settings_Old while Illustrator is closed.
Manual Method (macOS): Go to ~/Library/Preferences and rename the Adobe Illustrator [version] Settings folder. 2. Fix Text and Object Corruption Go to Edit >
The error often triggers when Illustrator cannot process specific vectors or overflow text in a bounding box.
Expand Overflow Text: If you get the error while resizing a text box, try expanding the box manually to reveal hidden text before performing other edits.
Convert to Outlines: If the error occurs during a save, select your text and go to Type > Create Outlines. This removes font-related dependencies that may be causing the conflict.
Simplify Paths: Complex artwork with thousands of anchor points can overwhelm the preview engine. Select your art and go to Object > Path > Simplify to reduce complexity. Fix unknown error issues in Illustrator - Adobe Help Center
