Unable to start on macOS 10.15.6

After installing Zulu and installing Dataloader v50.0.0 I get the following error on startup. The same issue occurs with versions back to v45.0.0:

Still facing this issue. Have installed v44.0 with jdk8

Facing this same issue has taken so much of my time. I've tried different combinations of JDK and data loader versions, as well as Zulu version. Nothing works.

I found a way to make this work. Here's a link to my description of how I did it. I hope it helps you.

Closing as v51 (latest release) supports Big Sur.
