UF2 problem of STM32F103

[aihk]

I brushed STM32F103 through UF2. I found that the Bootmagic Lite function cannot be used. Can I only enter the guidance again through the reset button?

The firmware needs to have support for the particular bootloader you're using. AFAIK STM32Duino is the only bootloader supported for F103 boards, but it is fairly simple to add a new one: https://github.com/qmk/qmk_firmware/tree/master/platforms/chibios/bootloaders

Assuming its the same bootloader, #19594 should cover this. Feel free to reopen if it is a different bootloader.
