A lot of this depends on your threat model and how much of a target you think you are.

If you are worried about your safety, it's better to leave than figure out workarounds. And it's likely easier to get out before things get bad; consider going on an international vacation --- if things look fine, enjoy your trip and go back; if not, figure out what comes next from there.

If you aren't really worried about your safety, but just want to avoid getting hassled about communications and don't want to lose communications with the outside world... Definitely do encrypted messenger stuff. But also, try to set up alternate communications. Even though they're not hard to block, many government shutdowns don't block fixed line internet service, land line telephones, or international voice calling. If you can setup a dial-up internet account with an ISP in another country, you may be able to use that from your landline even if internet via domestic ISPs is all shut down. Of course, if the regime is interested, your telephone company would have records of the calls (at least destination and length) and that might get you put on a list.

But also note, if most of your contacts are local, and local communications are disrupted; having access to international communications doesn't help you communicate with your contacts, unless they've done the same thing and the more people who have set it up, the more likely it is to be noticed.
