… Another glitch, which sometimes happens: many apps - especially the “heavy” ones - suddenly won’t launch anymore, after bouncing in the Dock for some seconds; and this can usually be fixed by issuing a sudo purge in the Terminal: so, probably, memory-related (BTW, Howard of The Eclectic Light Company has often said that the Finder has a memory leak in Sonoma, but I don’t know if this glitch can be related to that).
