my-RIO connectivity issue

[SAM_NI]

I'm using PWM FPGA Top Level.vi

and its host example.vi

after running these VI's I received an error

and

to ensure the connectivity of my-RIO 1900, I checked its status from NI MAX

as you can see from this picture that NI my-RIO is connected.

Can anyone help resolve the issue or suggest a way to tackle this error.

Your help will be appreciated.

Please attach the entire project especially the .lvproj file.

The code you attached appears to be for a single-board RIO.  The myRIO-1900 requires the myRIO Software Toolkit, the two-most-recent of which are the myRIO Software Toolkit 2019 and myRIO Software Toolkit 2021.  These work specifically with LabVIEW 2019, 32-bit (I believe -- have never tried with 64-bit LabVIEW) and LabVIEW 2021, 32-bit, running on Windows 10 (I haven't tried, but I'm quite confident these will not work on Windows 11).
