Hi @Vero,
Apologies for the late response. I am on Sonoma 14.5 which I believe is the latest version of macOS. I am currently using Alfred 5.5 [2257] which I also believe is the latest. For me, the issue is intermittent to begin with. I would say on average it happens 3-4 times a day and usually the appearance of the input box is pretty quick AFTER a delayed appearance; after a couple of hours, it shows up delayed again. Reboots have not been fruitful in permanently solving this particular issue. I will test it out with a different input and come back with findings, but I don't believe it to be a hotkey conflict since that should cause the delay for every attempt (I think?).
