The browser automatically starts, ignoring the disabling of this setting when the PC starts.

I have a problem with the browser automatically starting when I start my PC. I have this feature disabled (!) ("Open Firefox automatically when your computer starts up" turned OFF) Everything was fine, but then I started using the "profiles" feature - browser start's to open automatically when i start up my pc. when I created a new profile (in addition to the main one). The problem appeared, and that was a long time ago (at least half of year ago it was already as now). I hoped that it would be fixed and didn't write to support. Windows and the browser itself have been updated several times since then - this did not help. Changing the settings in different profiles, creating / deleting them, and other basic actions did not help. What happens is that the browser ALWAYS opens when I start the PC (Profile selection tab, i have turned ON "Select profile when Firefox start up") I tried turn off \ delete all plugins, turn on\turn off almost every default setting, no effect. What should i do? Browser version - 150.0 (64-bit) (from "settings-about firefox") Windows 11 Pro 25H2 Currently have 4 profiles in Firefox - but problem appeared after creation on 2nd profile. "Open Firefox automatically when your computer starts up" turned off in every profile.
