NCP update failing: ./update.sh: No such file or directory

Hey everyone,
I am running NCP on an Raspberry Pi 4. At some point I must have taken the “wrong” updater (the NC internal updater), so I am now on NC version 22.2.3, but still on NCP version 1.37.2. Using nc-update leads to the following output:

[ nc-update ] (Tue Jan 25 21:38:38 CET 2022)

/usr/local/bin/ncp-update: line 23: ./update.sh: No such file or directory

ncp-report results in the following info:

Does anyone know how to fix this and update to the newest NCP version?
