I used Windows 11, and the File Explorer on the taskbar keeps crashing. To find out the reason: Click Control Panel, then System and Security, then Security and Maintenance, then Maintenance, and finally, View reliability history. Locate the crashed software, and click to view the reason. Later, I found that explorer.exe crashed, BIB.dll_unloaded. Later investigation revealed that Windows 11 had installed Photoshop CS4. Yes, I happened to install it yesterday.
