How OpenShot was installed? Add output of `apt-cache policy $(dpkg -S /usr/bin/openshot-qt)` .

I can't reproduce the issue by adding official PPA to my fresh Ubuntu MATE 20.04.3 LTS system. I did the following:

sudo add-apt-repository ppa:openshot.developers/ppa
sudo apt-get update
sudo apt-get install openshot-qt

So you have to check your Qt installation. I would recommend to reinstall Qt Network library with non-standard _ZN15QIPAddressUtils8toStringER7QStringPh symbol. Use command below:

sudo apt-get install --reinstall libqt5network5

and retry launching Openshot.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
