There is no official freifunk-generic theme in 21.02 or master.

The third-party unsupported theme is known to be broken.
(the Freifunk feed with the broken theme is still present in 19.07, but the contents of their repo are outside OpenWrt control)

so do you have any solution from this problem sir?

Use a supported normal theme...
Bootstrap, Openwrt or Openwrt-2020

Use opkg from SSH console to return to the default bootstrap theme, or to install e.g. luci-theme-openwrt-2020.

opkg update
opkg install luci-theme-openwrt-2020

The theme is set with /etc/config/luci, so you can also edit that config file directly (with an text editor like nano or vi).

The relevant lines should look like this.
The mediaurlbase line selects the theme from the installed ones:

root@router1:~# cat /etc/config/luci

config core 'main'
        option lang 'auto'
        option resourcebase '/luci-static/resources'
        option ubuspath '/ubus/'
        option mediaurlbase '/luci-static/bootstrap'
...
config internal 'themes'
        option Bootstrap '/luci-static/bootstrap'
        option OpenWrt2020 '/luci-static/openwrt2020'
