Crash upon use of a certain VST plugin that does not occur in previous LMMS versions

[NewActiveXObject]

System Information

Windows 10 (x64), Intel Graphics HD 5000

LMMS Version(s)

1.3.0-alpha.1.813+9cb3ae7

Most Recent Working Version

1.3.0-alpha.1.690+gd703f3915

Bug Summary

Briefly: I upgraded LMMS by selecting a newer version and kept a handful of older projects with the AuraPlug VST effect Red Skull, which functioned wonderfully in the previous version reported. Now, the VST does not load at all, which is shown:

• Through reporting with a message box that "The following errors occurred while loading: the VST plugin RedSkull (x64).dll could not be loaded."
• The following (portion) of console output appears, taking a sample project as an example:

Unable to open default EUDC font: "C:\WINDOWS\FONTS\EUDC.TTE"
Cannot load library C:\Program Files\LMMS\plugins\carlarack.dll: Impossibile trovare il modulo specificato.
Cannot load library C:\Program Files\LMMS\plugins\carlapatchbay.dll: Impossibile trovare il modulo specificato.
Cannot load library C:\Program Files\LMMS\plugins\carlabase.dll: Impossibile trovare il modulo specificato.
[...]
unique ID: afs1
RemotePlugin::DebugMessage: inputs: 2 output: 2
RemotePlugin::DebugMessage: creating editor

[...]

Expected Behaviour

Red Skull should load.

Steps To Reproduce

Download the plugin from any trusted repository and select it from any instrument.

@NewActiveXObject thanks for reporting this. I've reproduced and milestones this for the 1.3 release which we're working towards.

• The 32-bit VST effect seems to work fine.
• The 64-bit VST crashes and does NOT work.

For now, please switch to the 32-bit VST effect until we can find someone to debug this further and thank you for finding bugs with our nightly version, it's greatly appreciated! Please feel free to tag myself directly for more items that directly related to the nightly branch. If you're interested in getting formally involved with our testing team, feel free to ping me on Discord https://lmms.io/chat
