For people searching for the same problem, it was fixed by removing libobs0t64:amd64

The hint was that the executable loaded libobs from this location:

$ ldd /usr/local/bin/obs | grep libobs libobs-frontend-api.so.30 => /lib/x86_64-linux-gnu/libobs-frontend-api.so.30 (0x000070ee94b31000) libobs.so.30 => /lib/x86_64-linux-gnu/libobs.so.30 (0x000070ee91cf3000)

and that location wasn't from the compiled version, it was from a system package:

$ dpkg -S libobs.so.30 libobs0t64:amd64: /usr/lib/x86_64-linux-gnu/libobs.so.30

$ dpkg -l libobs0t64:amd64 Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-================-===================-============-============================================================= ii libobs0t64:amd64 30.0.2+dfsg-3build1 amd64 recorder and streamer for live video content (shared library)

with that deleted it went to search for the correct version:

$ ldd /usr/local/bin/obs | grep libobs libobs-frontend-api.so.30 => /usr/local/lib/libobs-frontend-api.so.30 (0x00007f6fcdb80000) libobs.so.30 => /usr/local/lib/libobs.so.30 (0x00007f6fcaced000)
