1.17 Server hangs when starting after "Saving config files." is logged

[trevorjwilliams]

Describe the bug
After following the installation instructions and configuring fdlink.json, Minecraft fails to start, hanging after the following lines are logged:

06:31:18] [main/INFO]: Initializing 1.16 Compat module
[06:31:18] [main/INFO]: Looking for config file(s).
[06:31:18] [main/INFO]: Reading config file(s).
[06:31:18] [main/INFO]: Config files read.
[06:31:18] [main/INFO]: Saving config files.

Reproduction steps

1. Install and configure the addon on a 1.17 server
2. Start the server
3. Server hangs indefinitely as described above. Removing the addon allows normal functioning to return.

Expected behaviour
The server should have been able to start.
