FlexASIO no longer opening after changed settings - Ableton Live 12

[egallajasmine]

Hi there,
I have been having issues with crackling and stalling while playing and recording so I fiddled with some settings in the FlexASIO configurations, trying to see if using various backend options would help but since most of what I've tried to read about the backends and latency settings goes way over my head I think I screwed something up because now it won't open at all and when I choose FlexASIO as the audio driver Ableton Live says:
The audio engine is off. Please click here to choose an audio device from Live's audio preferences.

BTW, I don't know if it's helpful to know, but when I choose either MME/Directx or ASIO4ALL v2 the audio output works mostly fine with occassional hiccups but the reason I can't use them is that neither works well for recording using my microphone.

Here is what my FlexASIO log file said when I tried to start FlexASIO:

Thank you!

The answer is right there in the log you posted:

Invalid configuration: in option 'bufferSizeSamples': buffer size must be strictly positive

Your configuration file contains the line:

bufferSizeSamples = 0

Which does not make sense. Either set the option to a proper value, or remove the line entirely to use the default buffer size.

Okay, thanks, I thought that was what it was saying but since I didn't ever touch the buffer size numbers I didn't see why it would have changed from default. So since my flipswitchingmonkey GUI is not working now and won't come up at all since the FlexASIO won't initialize then can you point me in the direction of how to remove the line entirely and return it to the default buffer size?

Thank you!

The configuration file is located at C:\Users\(your username)\FlexASIO.toml. See the documentation for details.

If FlexASIO GUI wrote bufferSizeSamples = 0, then that's definitely a bug in FlexASIO GUI and you may want to report it against them.
