[Linux] Error in MatlabWindow after upgrading Ubuntu from 20.04 to 22.04

Have an error with MATALBWindow occouring when trying to run simulink in Matlab 2018b after upgrading to Ubuntu 22.04. Matlab doesnt give a name for the missing package so have assumed its a missing package nested deep or an incorrect package version after upgrading.

Traced it as far as running MATLABWindow from command line and doing an ldd of the offending package.

./MATLABWindow: symbol lookup error: /lib/x86_64-linux-gnu/libpango-1.0.so.0: undefined symbol: g_memdup2

Not used to solving linux problems yet so any help diagnosing the issue is appreciated.

Currently using two versions of Matlab: 2023b and 2018b.

And no, I cannot upgrade 2018b (need it for HDL coder).

According to this, up to Ubuntu 18.04 LTS is supported by MATLAB R2018b.
