Manager IO not functioning in my Computer

I flagged your opening post because you keep opening and responding to topics about the same. We also asked you multiple times including by the develooer to provide more details. If you want us to help you you should not crosspost and supply the information requested,

Also look at the recent post by @Lubos on supported operating systems:

As for Windows Requires Windows 10 (64-bit) or newer and for Linux Requires Ubuntu 20.04 (64-bit) / Fedora 38 (64-bit) or newer
