confirmed. The original exe from you works. Please close this. sorry for disturbance.

Win10 2.50(64bit)+keepasslibc 1.40-0x01BC. It's a portable version from PortableApps.com. But I doubt it's related to their packing. It formerly worked well.

I put the portable version on cloud, using it from two places. Everthing is fine...
