I'm experiencing the same issue since quite a while.
I have a 2017 MBP 15" with Touch Bar where I'm switching between clamshell-mode with an external (32"/4K) display and the builtin display without an external display connected.
When I plug in the external display, the MBP is usually sleeping.
I'm not sure if it happens everytime, but quite often when waking the MBP then, snap areas are not working (they are not displayed on the screen and a keyboard shortcut assigned to one of them also stops working).
I have to restart BTT to make them work again.
I still have this issue. It's not occuring every time I switch from the builtin display to the external one, but it happens quite regularly.
One workaround was to enable "Restart BTT after wake from sleep" in the Advanced/General settings section.
This introduced a slightly annoying delay after waking up until BTT shortcuts were available due to the restart of the application (but still something that I could live with).
I'm running macOS Ventura now and now I often saw BTT re-requesting accessibility access after waking up with the "restart on wake" option enabled, so I disabled it again.
Anyway, if no cause for the snap area issue can be found, how about a "re-initialize snap areas on wake up" option? This should solve the issue without requiring a complete app restart.
I have also added more debug logs in recent versions, would be great if you could go to help -> export diagnostic debug information and send the result to me (firstname.lastname@example.org). Maybe these logs allow me to see what’s going on.
Similar issue is happening to me, except I'm using better snap tool 1.9.8. I have to quit and relaunch the app constantly, as the snap areas stop working. not sure if it's only on wake, though. Feel like it happens sometimes while I'm actively using the computer.
Running 3x pro display xdr mounted vertically, with 9 custom snap zones on a mac studio. been an issue on ventura since the beta launched, and I believe since Monterey as well but I don't recall 100%
Never had an issue on the same Mac Studio with my old monitor setup, which was 2x pro display xdr horizontally, plus 2x LG ultrafine 4k (also horizontal).
Not sure if it's a coincidence or not, but I noticed the problem right around the time I upgraded monitors.
Happy to provide any data I can to help with troubleshooting. How do I provide this with the snap tool app?
