Gain-dependent SDK errors while taking flats with ASI2600MC Pro in NINA

I've run into a problem while taking flats with NINA 1.10.HF1 (the latest version) on Windows 10. The camera is 2600MC Pro.

The problem: I can take flats with gain 115 or higher. If I lower the gain to 114 (without changing anything else), NINA reports SDK errors, as seen in the screenshot.

The exact sequence is as follows:

connect camera to computer
start NINA and connect the camera in NINA (note my default offset is set to 50)
start Flat Wizard, set gain to 115
initiate the wizard (note: you may need to adjust exposure or step settings, depending on your light source)
the above should complete fine
close NINA, disconnect camera.
reconnect camera to computer
start NINA and connect the camera in NINA
start Flat Wizard, set gain to 114
initiate the wizard
the above will give the errors seen in the screenshot

I've posted this on NINA's Discord support channel and they said it's a problem with the SDK and suggested I contact you.

Thanks and let me know if I can do anything else to help.

These are the camera settings in NINA:

And one final comment: the error does not appear if I use the camera with the ASCOM driver from within NINA. Only when using the native driver embedded in NINA.

hello please try on the ASIstudio（the native driver）
