The log will be the best bet, hopefully we can see how far it got before it died. Even if the log is incomplete due to crashing, I'm hoping we can find some type of bug that has been hiding for a while and has been exposed.I just installed Kodi 18.2 and the latest DVR PVR Client on a Firestick TV for a friend who has a Prime 3 with a cable card. Kodi ran fine. After I installed the PVR Client, it started to pick up guide data and then Kodi crashed within seconds. Tried this on a new Firestick 4K, same problem. Tried going back to your apk build of 17.6 with the PVR Client bundled in. Same crash. Brought the Firestick to my house where I'm using a Quatro HDHomeRun tuner and it worked fine on 18.2 with the latest client (as do all of my firesticks). The HDHomeRun app works find at my friends house on the firestick. This friend had it all working last fall, but we took it out of service for a home remodel which is now done. FYI, the client is trying to pick up the guide data for about 80 channels.
Any ideas? I'll try to get a log file. I'm thinking I'll start it up, let it crash, then disconnect the Prime 3 tuner from the network and start it again. Hopefully it won't then crash and I can get the prior Kodi log....tomorrow.
Did you perhaps try an older build, maybe prior to v2.0.0? v2 had a great deal of changes in it. To date, I've only found one issue that caused an exception (setting/clearing a channel as a Favorite or deleting it), but while I try to test everything every time, the track record appears to be that I will always miss something
