Steps to reproduce the problem:

1. Execute texworks -v from command line.

Expected behavior:

Show version info as in Menu > Help > About TeXworks... would display in the GUI program.

General information:
TeXworks version: 0.6.6 (MiKTeX 22.1)
TeXworks obtained from: Ubuntu ppa
Operating system: Linux linux 5.4.0-65-generic #73~18.04.1-Ubuntu SMP Tue Jan 19 09:02:24 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

So far, I cannot reproduce this, neither with (the outdated) 0.6.6 nor with (the current) 0.6.7. For me, the 0.6.6 version prints TeXworks 0.6.6 ("launchpad") [r.24442ac0, 11.03.21 11:03] on the command line and also displays Version 0.6.6 ("launchpad") [r.24442ac0, 11.03.21 11:03] in the "About" dialog. What do you see in the "About" dialog?
The only thing that might be different is the calculation of the date/time, which uses the system locale (see main.cpp@l84). The rest should be just fixed, static data set during the build (which would not show up on my system either if it were corrupted somehow). What locale/time settings are you using?

The About dialog displays Version 0.6.6 (MiKTeX 22.1) [r.24442ac0, 3/11/21 6:03 PM].
Anything more I can try?

The fact that it says MiKTeX 22.1 instead of launchpad suggests that you are using a binary built and shipped by the MiKTeX project, not the Ubuntu ppa. If that is the case, this is probably a problem in MiKTeX's building process and should be reported to the MiKTeX devs. Maybe they changed something to that particular part of the code for some reason.
