Screenshot of the error "Could not enter folder"

Hello. I hope I've chosen the right product and component.

There is one old smartphone (Sharp Aquos C10 on Android 10) that does not open
in Dolphin via MTP. It's accessible via android-file-transfer, jmtpfs, also
works without problems on Fedora Gnome (stock file manager) and Windows.

STEPS TO REPRODUCE
1. Plugin smartphone to USB (it's unlocked and MTP mode is selected).
2. The popup "Disks & Devices" opens next to the tray, where I see the device.
3. I click "Open in file manager" button, a window appears with the title
"Error - KIO Client" with text "The file or folder /Sharp Aquos C10 4/64 does
not exist".
4. I open Dolphin, phone is displayed in the left panel. I click on it and get
an error "Could not enter folder /Sharp Aquos C10 4/64" (screen #1). The path
is
mtp:udi=/org/kde/solid/udev/sys/devices/pci0000:00/0000:00:14.0/usb1/1-1/1-1.2/

I don't see errors in journalctl. However, I can access the files through
another applications:
1. android-file-transfer: launched, clicked "Kill users" button (to kill the
process /usr/libexec/kf6/kiod6, otherwise there will be an error "No MTP device
found"), then "Ok". I see the memory contents, can download and upload.
2. jmtpfs: command jmtpfs ~/mnt (also killed the kiod6 process) and I can open
this folder via Dolphin and also work with data.

The mtp-detect command shows the following (left just the beginning and I don't
know why "Nokia 6.1"):
