[KDE] Kde connect crashing kdeinit5 on sending files

[magus7091]

So yesterday evening, I was trying to transfer a file from my phone to my desktop using kde connect, and the send failed because I walked away with my phone absent-mindedly. I tried re-sending the file, and my phone just immediately failed to send. After trying a couple more times, I restarted the phone and computer to try again. Now, whenever I try to send a file, it still fails immediately on the phone, but I also get a crash report saying kdeinit5 crashed. I was able to use the PC side of kde connect to pull the file from my phone, and that finished successfully. I'm trying to figure out how to fix it, I thought maybe dpkg would help, but it says kdeinit5 isn't installed.
Background:
I'm running a much older HP media PC, don't know exactly the specs but it is running a quad core Intel processor and an Nvidia GeForce 750 graphics card.

Error dump:

Application: kdeinit5 (kdeinit5), signal: Aborted

have you tried clearing the app's cache?
Unpaired on both the PC and phone side, and then re-pairing?
Or even clearing the app data? Clearing data will reset the app completely, including paired devices etc.

As sending from the phone works fine, it seems to me it is more likely a phone app issue, less likely an issue on the PC side

Sending from the phone fails immediately, but browsing and copying files from the computer works. I'll try clearing the app cache on my phone, but what would I need to do from the computer to clear the app cache? I'm at work right now so I can't check but I assume there's a kdeconnect folder in .local? Or are you talking about a cache for kdeinit5? Please let me know and I'll post back with results this afternoon. Thanks!

I am talking about clearing the app's cache - on the phone.
Phone apps save data and also states, things not done on pc software usually.
Sort of like a sleep or suspend state.

That fixed it, thank you. I'd figured the problem had to be on the computer, since that's where the crash was being reported. Guess I failed to do basic troubleshooting this time. Thanks so much!!
