qtVlm fails to launch with missing shared libraries error

I periodically get this error when trying to launch qtVlm on Linux: error while loading shared libraries: libx86emu.so.2: cannot open shared object file: No such file or directory

It doesn't happen always.  For a while I thought by launching after a reboot and before launching any other apps I could avoid the problem, but that's not the case. The odd thing is that it only happens intermittently. Any suggestions?

This error is usual in case of a bad installation / missing libs. What is strange is that it is not hapening each time.
It would help to determine more precisely in which conditions it happens.
Also we could try to understand by looking where are the libs by doing this when qtVlm can be launched and in the case of issues

find /usr/lib /usr/local/lib -name "libx86emu*"

this gives on my side:
/usr/lib/x86_64-linux-gnu/libx86emu.so.2
/usr/lib/x86_64-linux-gnu/libx86emu.so.2.0
I extract the folder containing the lib (/usr/lib/x86_64-linux-gnu/) and do:
ls -l /usr/lib/x86_64-linux-gnu/libx86emu*
which gives me:
lrwxrwxrwx 1 root root 16 août 22 2019 /usr/lib/x86_64-linux-gnu/libx86emu.so.2 -> libx86emu.so.2.0
-rw-r--r-- 1 root root 153696 août 22 2019 /usr/lib/x86_64-linux-gnu/libx86emu.so.2.0

report us the result of find and ls in both cases
