Some conan packages don't install with Qt Creator

When I create a Qt-Application that depends on "sentry/0.7.15"(https://conan.io/center/recipes/sentry-native?version=0.7.15), CMake step fails in Qt Creator during processing of the conan install part as follows:

It seems as though the "conan install"-command that is executed from within QtCreator/CMake is supplied with a modified conan profile. My actual conan profile is as follows:

[settings]
arch=x86_64
build_type=Debug
compiler=msvc
compiler.cppstd=23
compiler.runtime=dynamic
compiler.version=194
os=Windows

but it seems that when the profile is used from within QtCreator it looks like this (note the value for compiler.cppstd is set to none.)

[settings]
arch=x86_64
build_type=Debug
compiler=msvc
compiler.cppstd=
compiler.runtime=dynamic
compiler.version=194
os=Windows

When I run a minimal project from the command line, the install process succeeds.

Steps to reproduce:

1. Create new Qt Application
2. add "conanfile.py" with the following content

from conan import ConanFile
from conan.tools.cmake import cmake_layout

class SentryDemo(ConanFile):
settings = "os", "compiler", "build_type", "arch"
generators = "CMakeDeps", "CMakeToolchain"

def requirements(self):
self.requires("sentry-native/0.7.15")

def layout(self):
cmake_layout(self)

3. ensure that Preferences>>CMake>>Package Manager Auto Setup is enabled
4. run CMake for the project

CMake should start running and while invoking conan install .... it will fail with the aforementioned error message.
