Intermittent freezes caused by Device add/removal

[calabrel]

I've played Phase Shift for years, but at some point in the last six months I've been getting consistent intermittent lag-spikes during gameplay and even during menus.  Looking at the logs, they lag-spikes seem to correspond to the follow entries:

Wed May 12 14:56:54 2021 - CtrlDevice::DeviceChange():Device Added/Removed Event Detected
Wed May 12 14:56:54 2021 - 1 MIDI Device Found

I cannot figure out why it's doing this.  I disconnected all my devices and used them one at a time and still it happens during each one.  I've even reformatted my entire PC and reinstalled Phase Shift (v1.27) and it persisted.

There was a thread here: dwsk.proboards.com/thread/2692/phase-shift-freezes-randomly-980ti

That got David's attention and he put out a beta build (v1.27g) which seemed to have corrected the issue for the user, but when I downloaded that version from the link he provided, Phase Shift wouldn't run.

Does anyone have any ideas as to how I can fix this?
