No, only delete the RC App from the Control Hub. If you delete the FtcAccess-PointService or any other app you’ll need to reinstall the Control Hub OS to restore it (that service is part of the Control Hub OS component).
From talking with REV support, there are a number of signs that may point towards file system corruption. If you check your log files, there are probably messages about blocks files being corrupted, and your inability to run the RC app no matter which version you’ve installed seems to point to this.
By the way, the blue LED on the Control Hub is actually controlled by the RC App itself; the blue LED is on by default which you’ll see it on while the device is powering/booting. Then when the RC app loads it causes the LED to blink blue while things are being initialized. Finally the RC app causes the LED to turn Green when everything is ready. Everything you’re describing with the LED and the inability to launch the RC app (and keep it launched) jives with each other.
Also when the app crashes, all communication sockets are then lost with it, so it makes sense that you’re getting socket errors. The only question is why the RC app keeps crashing regardless of which version is installed (and re-installed). Corrupted installation that isn’t being cleaned up properly and/or corrupted file system is the easy thing to blame, but it’s impossible to tell if it’s a red herring or not. Two systems being corrupted by being updated seems far fetched, but two systems being corrupted by the same computer/setup because of possibly a bad cable/connection or faulty software download (that somehow passed the checksum) is more likely, but definitely there’s no smoking gun that we can identify. Ugh, this is a nail biter.
I haven’t checked with REV, but I wonder what a factory reset does on the Control Hub. That’s when you use scrcpy to access the Control Hub, go to the settings menu, go to “Storage and Reset”, and reset to factory default. I hooked a monitor up to my HDMI output on the Control Hub so I could always see the display on the device, and I also plugged in my USB hub where I had my mouse and keyboard plugged in so that I could control the device. I then performed a Factory Reset. At that point if I’m using scrcpy, the connection drops as the device is doing whatever it’s doing - however, since I had a monitor hooked up to the HDMI output I was able to see the “Erasing” graphic and the Control Hub took about twice as long as normal to boot, but it eventually booted up and launched the RC app that was previously installed so I’m not sure what it erased. But, maybe try uninstalling the app, doing a factory reset, and letting the device reboot, and then reinstall the app? I don’t know if there’s a filesystem integrity check that goes on, but we can cross our fingers and hope?
I wish I had a better answer, at this point all I know is that something went bonkers. I’d recommend seeing what a factory reset (after manually uninstalling the RC app) does for you. Use a different USB cable and force the REV Hardware Client to re-download the apps it has, and try installing the software again (I would reinstall the Control Hub OS too).
Crossing my fingers for you.
