Try to connect the dongle(s) with an USB extension cable(s) or with an USB hub. Perhaps there's a high-frequency noise from RPi (or from the USB3 key) which breaks the dongle's wireless communication so it may be better if you move them as far as possible from RPi's board. Also try to replace batteries with fresh ones.
It worked, thanks!
The keyboard began to work normally, the remote is not working yet but I think this is due to a hardware problem.
Thanks again!
Depending on how old your RPi4 is, you may still have to update its firmware for booting and the USB3 controller. If that has not yet been done, then you'll have a challenge getting the RPi4 to boot from USB.
Booting goes fine and everthing works but not the keyboard and remote.
It is something like these devices do not receive enough current but I cannot read anything in the log e/o in dmesg.
Perhaps you can still fix the SD slot problem(s).
I think I will need some micro-soldering.
Hello,
I have a raspberry pi4 working fine booting from the sd card with libreelec stable and using a wireless microsoft keyboard and a remote with usb dongle attached to usb 2 ports.
But some days ago the sd socket broke a little and it is no more well attached to the motherboard.
So I used a usb key to boot the system using the usb 3 port and quite everything worked fine but the usb keyboard and remote are not working anymore because the key pressed are received only sometimes. I can control Kodi using the kore remote program and the web interface.
I tried to boot also with a usb ssd with external power supply but the problem remains.
I cannot see any clue in dmesg and kodi.log.
I have similar symptoms either with video and flac files taken from a NAS connected via ethernet cable (I tried to report this problem in [Raspberry PI4] Can't watch anymore movies).
I tried your hint with advancedsettings file but without solution: http://ix.io/2QWP here is the log trying to play a flac file.
I saw many lines with this error:

Neither can we, that is why we always prefer FULL debug-enabled log files, provided via a pastebin service/website.
Ok, I restarted the raspberry and I began to see the movie (about at 16:06) and the full log could be seen at kodi.log?t=8f2b2h47
Thanks a lot for any help, I like very much libreelec!
I have a raspberry PI4 (4g of ram) connected to my nas via ethernet.
Until three days ago I could watch movies and listening music fine but now watching movies is not possible because the playing jumps, the images are "mixed" and then it stops.
In the log I can see this error trying to see a movie .mkv (with mpeg-4)
