There is a path character limit in Windows Operating system. When do you get this error?
Check the article below. Especially Method 4.

This error typically shows up when the full file path exceeds Windows’ character limit (around 260 characters), especially in nested temp or AppData folders.

Even though Windows 10+ supports long paths, many applications — including older components — still choke on them.

You could Use a dedicated long path handling tool to rename, move, or delete the problematic folders. This avoids registry tweaks or risky manual edits in deep system folders.

Also, try clearing the %AppData%\Local\Temp or Studio cache — it can sometimes reset stuck files like Default.drm.
