Before knowing about how to fix this issue, you should know the reasons behind this trouble.

Why did you face the problem with the qBitTorrent I/O error?

 

Many possible reasons may cause qBitTorrent I/O error. Let’s get a clear idea about some possible reasons behind this issue.

 

Lack of permission

 

qBitTorrent requires administrative permissions to read and write on your computer partitions. This hurdle can be fixed easily by providing admin permission to qBitTorrent. It’s based on the Qt toolkit and so, it requires admin permission to run precisely.

 

Improperly configured Windows Defender

 

Sometimes, Windows Defender hinders qBitTorrent to run properly. Windows Defender detects qBitTorrent as harmful software and for this reason, it can’t work properly. The main reason behind this problem is the incorrect configuration of Windows Defender. To eradicate this problem, you have to permanently disable Windows Defender. Alternatively, you can ensure the proper authorization so that qBitTorrent downloads don’t get blocked anymore.

 

Antivirus issue

 

Third-party antivirus works similarly to the Windows Defender. It blocks downloads from qBitTorrent due to the lack of proper configuration. The most effective way to resolve this trouble is disabling third-party antivirus on your PC forever.

 

Incompatible processes

 

Like other software, qBitTorrent has compatibility issues with other applications. The apps are functionally built to clash with qBitTorrent activity.
