Starting with kernel 6.3 the rtl8xxxu module will support this chip. You should blacklist it in order to keep using this module without problems.

Linux 5.15 kernel has Realtek RTL8118EU WiFi driver support natively - it should be safe to uninstall the 8188eu-dkms package

Please add the patch for Linux 5.10 support:
