Proxmark3rdv4 BT - blinking LED, no standalone mode

I have a proxmark3 rdv4 with the blue shark connected. The issues appear to happen with or without the blue shark connected. At one point everything appeared to work with the device before using the blue shark, but it had been a while since I used it. Ideally I would use the device with the Walrus app for red team engagements, however that no longer works now. The Walrus app sees the device but won't read any cards. When used in stand alone mode the leds do not display what I am use to seeing. For example the "D" led blinks. No cards appear to be read. When I connect via USB cable to my computer  and do a lf or hf search the proxmark will read cards. Have not been able to clone cards read but I think that is user error.

These may be all separate issues, probably starting with my lack of knowledge. But the issues I see are:

I can't use standalone mode.
I can no longer use the Walrus app
The LED lights do not line up with what Ive seen in the past such as the blinking "D" led.

Some of what I saw was:
when flashing A and C led are on
when done flashing all leds are off
hold button for ~2-3 seconds,  each led turns on and then off in a pattern then led A is solid and led D is blinking, no other options for the leds.

Re: Proxmark3rdv4 BT - blinking LED, no standalone mode

Thank you for the assistance. I flashed an older version and removed the blue shark and the stand alone function works now. Is there a version I can use with the blue shark for stand alone?

Obviously it goes without saying I am new to this so again the assistance is much appreciated. I have an opportunity to use this on an engagement is a couple of months and for the first time I am actually trying to prep well ahead of time!

Thanks

Like the issue says,  use the release version and compile how you want it
