Dynmap crashes on server startup

[DrSawickipedia]

I'm having an issue when trying to load the most recent Dynmap (3.6-beta2-fabric-1.20) using Quilt 0.19.1 on MC 1.20.1. I saw that this was an issue in the past, and added -Dloader.workaround.jar_copied_mods=dynmap to my startup arguments, but I still crashed (with the log/crash report for this attached). If I don't include that line (or include another name besides dynmap, like minecraft), then it crashes much earlier with the error: java.lang.RuntimeException: Could not execute entrypoint stage 'main' due to errors, provided by 'dynmap'!

Other notes:

• I'm using fabric api rather than quilted fabric, as that was causing issues with some of my other mods
• The server was configured with the other mods first, with dynmap added later
• This issue does not occur when using the Fabric loader, with everything else set up the same

I originally asked this question on the Quilt Discord, and was told to report it here
