problems with Conan+QtCreator+Windows

[r3d9u11]

Hello. I've just tried to configure QtCreator+Conan (experimental plugin) on Windows, but something went wrong. It can't detect compiler:

14:31:42: Starting: "C:\Program Files\Conan\conan\conan.exe" install -s "build_type=Debug" "--build=missing" C:\Users\User\Desktop\Configurator\conanfile.txt
Configuration:
[settings]
arch=x86_64
arch_build=x86_64
build_type=Debug
os=Windows
os_build=Windows
[options]
[build_requires]
[env]

ERROR: boost/1.78.0: Error in config_options() method, line 262
  if self.settings.compiler.cppstd:
  ConanException: 'settings.compiler' value not defined
14:31:43: The process "C:\Program Files\Conan\conan\conan.exe" exited with code 1.
Error while building/deploying project Configurator (kit: Desktop Qt 6.2.2 Clang)
When executing step "Conan install"

Kit:

• In that time the same configuration on Linux works perfectly:

14:21:04: Starting: "/usr/bin/conan" install -s build_type=Debug --build=missing /mnt/storage/Projects/Targets/Configurator/conanfile.txt
Configuration:
[settings]
arch=x86_64
arch_build=x86_64
build_type=Debug
compiler=clang
compiler.libcxx=libstdc++
compiler.version=10
os=Linux
os_build=Linux
[options]
[build_requires]
[env]

Does anyone have any ideas?
Thanks!
