Just to clarify: is the Nektar SE49 connected and/or powered on before launching Reaper?
Otherwise, there's also the option to use
Reset all MIDI Devices to rescan the MIDI device list:

Normally, the 'error opening device' window is displayed when a MIDI device (that is enabled in the Preferences) is currently not connected or already in use by another application.
It's possible to hide this warning window by using the
Do not show this window again checkbox at the bottom left. Or to toggle this warning window on/off via the
Warn when unable to open MIDI devices checkbox in
Preferences > Audio.
Side note: the general recommendation is to connect a USB device always to the same USB port (if possible). Because, as example, if you're on Windows, connecting the MIDI device to a different USB port can result in getting a different device ID assigned (one for each USB port the device was connected to once). And you'll have to re-enable the MIDI device (with the correct ID) again in the Preferences.

If the problem persists, can you please post screenshots of your current settings:
- Preferences > Audio > MIDI Devices
- Preferences > Control/OSC/web
