I had Slido v1.18.0.6804 installed and worked well in powerpoint. After I quit Powerpoint, it updated to V1.18.0.6918 and is no longer working. The ribbon button is not showing properly and nothing happens when I click it

When I run the slideshow, the startup slide presents like this

instead of the showing the QR code. The palette is also not showing. I have my presentation in two weeks.
