Error when using std::from_chars with g++-10.2.1

So, unfortunately, I cannot reproduce the error, since it seems to be fixed in newer g++ versions, but I cannot compile the following code:

#include <charconv>
#include <concepts>
#include <optional>
#include <string_view>

template<std::floating_point T>
std::optional<T> to_float(std::string_view s)
{
    T value;
    if (std::from_chars(s.data(), s.data() + s.size(), value).ec == std::errc{})
        return value;
    return {};
}
  
int main()
{
    to_float<float>("0");
    return 0;
}

It yields the following error:

I'm using g++ version is g++ (Debian 10.2.1-6) 10.2.1 20210110. Any ideas how I can solve this issue? Using a newer g++ version is not possible, unfortunately.
