Plugin cannot open when target soundfont is not found where expected

[HLRxxKarl]

I tried opening a project file from 3 years ago that used this plugin. In that time, I've since upgraded and renamed the hard drive the project file was on. And I assume that's the reason why the plugin cannot open in those old project files. It loads fine when I open a blank instance from my plugin database. But anything that previously had a soundfont loaded can no longer open at all. And this happens to be on plugin instances that had unique ADSR values, so I would like to get them working again so I can recover those values. It's fine with me if it can't locate the SF2 file. But I'd rather it just load without the soundfont than not load at all.

This issue is happening in FL Studio 21.2.3 build 4004 64 bit on a Windows 11 computer. The plugin instance attempting to load is the VST 3 version. I tried doing a fresh install of the plugin and rescanning my plugin database, but neither fixed the issue.
