BetterTouchTool not launching at Startup Mac Big Sur

The BetterTouchTool ver 3.561 is not launching at startup on the Macbook Pro 2016, Big Sur 11.2.3
I have the Launch BetterTouchTool option selected in General, Basic settings and it is in the Login Items in User & Groups on the Mac. I have uninstalled and reinstalled it but it still doesn't launch at Start, any ideas for what I can try to get it launching at startup?
Thanks a lot

I've been having the same issue. Super frustrating. I am now up to Big Sur 11.4 (20F71) and BTT 3.560 (1700). You find anything?

I am on Mojave and have same issue.version 3.579(1722)
My app is in applications, however when I try to update it tells me it can not update from an optical drive or read only drive and to put it into applications and try again.

Still happening on Ventura.
