Unable to input Chinese using palm input method

System information

windows 10

Issue description

Only palm input method can't input Chinese, other input methods such as Microsoft Pinyin, Sogou Pinyin, qq Pinyin, Google Pinyin all work.
Through git bisect, I found that it was introduced from #75881.
By adding CoInitialize(nullptr) to OS_Windows() in platform/windows/os_windows.cpp I can get it to work, but I'm not sure if it causes other problems.

CoInitialize() is technically CoInitializeEx() with COINIT_APARTMENTTHREADED. I'm not sure whether changing to COINIT_MULTITHREADED was to solve other problems. CC @bruvzg

It was changed to fix multiple crashes (#74288, #73039, #74396, #71835), but I'm not sure if COINIT_MULTITHREADED is absolutely necessary or simply removing excessive calls was enough. In any case, there should be only one CoInitialize(Ex) call.
