Hello i have a SKR board and the MCU was faulty. I swap the chip and tried to conect via SWD on CubeProgrammer but no success after i have can connect via usb but when i as to program by my mistake i erase full chip and after cannot conect again.
Is there some way to conect the chip or is broke?

Pull up BOOT0 (SWCLK) to VDD and connect in USB DFU mode.
By the way, looking at that schematics...

No idea, not my board, got a schematic?
The ST-LINK would likely need VCC-TARGET, GND, SWDIO, SWCLK and NRST.
Try Connect Under Reset options
Try Slower SWD clock speeds for CM0(+) parts

If BOOT0 pin is pulled HIGH, can it connect to PC via USB as "STM32 BOOT DEVICE" type of thing? If so FW could perhaps be pushed by USB/DFU mode in STM32 Cube Programmer.
Talk to the Vendor, Read ALL the instructions.
