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

Dynmap expects all mods to be available as Files, which is why the workaround doesn't work - you'd need to list every single mod ID. Since that's obviously unreasonable I'll add another workaround option to jar-copy all mods. Ideally though this would be fixed in dynmap (they should be able to use the Path api instead), but I'm unsure of how many changes they would need to make internally.
