Not sure that can help.

You can try to read back FUS state and version with CubeProgrammer connected using USB (not ST-Link) with BOOT0=1.

By experience, It seems CubeProgrammer cannot read back FUS state using SWD.

If you have access to Linux or macOS, the psdb tool can be used to upgrade your FUS. Instructions here: https://github.com/tgree/psdb
