What type of Cloud API are you using?
Is it Azure API or third-party API like AWS?
Did you face this issue in Windows 10?
Hi @Jojo Tang
As windows 11 is not stable yet you can try raising this to the Microsoft through the feedback Hub. This might be noted and resolved in the Stable version.

Why to uninstall using Cloud API App??
crash in cloud api and code implement as below
HANDLE ProtectedHandle;
HRESULT hr = CfOpenFileWithOplock(filePath, CF_OPEN_FILE_FLAG_EXCLUSIVE, &ProtectedHandle);
if (SUCCEEDED(hr))
{
hr = CfConvertToPlaceholder(
ProtectedHandle,
pPlaceholderData->FileIdentity,
pPlaceholderData->FileIdentityLength,
CF_CONVERT_FLAG_MARK_IN_SYNC,
nullptr,
NULL);
CfCloseHandle(ProtectedHandle);
}
call CfOpenFileWithOplock before using CfConvertToPlaceholder, why multithread access will crash in CfConvertToPlaceholder??
If possible try perform the same testing environment in Windows 10 and see if the problem persist?
I advise you to report this issue using the Feedback Hub app , so the Windows team would be able to investigate.
Windows 10 work fine.
Only crash in Win11
II had update to Feedback Hub.
