you need icu-60 https://github.com/unicode-org/icu/releases/download/release-60-3/icu4c-60_3-src.tgz
unfortunately, you need to build it from source

I haven't tested this yet on newer Ubuntu version, but it might be easier to build against the system package for Qt. In general, I'd like to make it more common practice to build TeleSculptor against system packages on Linux systems where the system packages are compatible. There are new CMake options to support this. For example, there is an option TELESCULPTOR_USE_SYSTEM_QT and similar for several other third party dependencies.

In case of flatpak, I fail to build from source so I bundled icu60.
