I'm have a weird problem--it looks like our addin is getting loaded twice, but only with a "Release" version! The debug version works properly--neither of the release tabs work correctly. Both are compiled using the same codebase. The problem shows up in both swx2023 and 2024, and seems unique to my computer.

I tried repairing SolidWorks, but no change. I suspect something's hosed up in the registry,
