This problem occurs both on my desktop and laptop when external displays are connected and trying to drag a file on an explorer window displayed on an external monitor to a Premiere Pro window displayed on the primary monitor. When the file-attached mouse cursor reaches to PPro window the whole system stops responding except a cursor and reboots after a while. BSOD is displayed sometimes.
This does not always happen. It occurs when the project is somewhat complexed or has many items imported.
desktop: OS: Windows 10 CPU: i9-10900k GPU: RTX 3090 RAM: 64GB display: primary (3840*2160), secondary (1920*1080), The primary monitor is scaled to 125% by windows display settings.
laptop: OS: Windows 10 CPU: Ryzen 7 4800H GPU: GTX 1660 Ti RAM: 32GB display: primary (1920*1080, internal), secondary (1920*1080)
both on my desktop and laptop: The operating system and all source files are stored in SSDs. Chipset driver and graphics driver are installed and up to date. Premiere Pro v14.9 is installed.
Premiere does not necessarily get the metadata from a file properly ensconced into the internal databases when you do drag/drop from Finder/Explorer. At the least, right-click in the Program monitor and select "import" ... but the vastly more stable method is to use the Media Browser.
And ... for many people ... once you learn how to set folder locations as a 'favorite' it's very fast to import/ingest media that way.
