Bug Description

The frpc.exe is reported as a threat. Is there away to solve this issue?
frpc works well for me on Linux/amd64, Linux/mips64el, Linux/Loongarch, Linux/arm64, Linux/riscv, OSX/amd64, Win10/amd64, Win 11 Pro/amd64, but not working on Win 11 Pro WS/amd64 and Win 11 Enterprise/amd64. All virus databases are up-to-date.
I know this is a false alarm, but I am not able to modify the windows defender settings.
Also, I know I can use wsl bypassing this issue somewhat, but this is not convenient and not providing complete features on host system.
Already tried to build from source code, as long as frpc.exe was built, windows will report it as a "threat" and delete the file.

frpc Version

from 0.66.0 to 0.38.0

frps Version

from 0.66.0 to 0.38.0

System Architecture

windows/amd64, win11 Enterprise, 25H2, 26200.7462; Win11 Pro Workstation, 25H2, 26200.7623
