Hello,
thanks for your hint. With that, I do not even get that far:
src\SettingsManager.cpp: In member function 'bool SettingsManager::loadWifiSettings()':
src\SettingsManager.cpp:5:17: error: control reaches end of non-void function [-Werror=return-type]
5 | Preferences preferences;
| ^~~~~~~~~~~
src\SettingsManager.cpp: In member function 'bool SettingsManager::loadAppSettings()':
src\SettingsManager.cpp:17:17: error: control reaches end of non-void function [-Werror=return-type]
17 | Preferences preferences;
| ^~~~~~~~~~~
cc1plus.exe: some warnings being treated as errors
*** [.pio\build\esp8622\src\SettingsManager.cpp.o] Error 1

and later
src\main.cpp:293:30: error: no matching function for call to 'fs::FS::open(const char [2])'
