No trophy icon even tho I just started?

[Soul]

Title,I literally just bought the game,no achievements yet,start a Isaac run on hard,and I see that "trophy block" icon,curious I go check online,and apparently that prevent me from getting achievements.
Why I get that? I literally just started,no mods,no challenge,just base run,I'm genuinely confused

Disable all mods and make sure the debug console is disabled as well.
Check here how to enable the debug console, just put it at 0 instead of 1 to disable it:

You can enable them again and still unlock things once you've unlocked the Womb (first Mom kill, in-game secret number 4). Before that point, they prevent all progress. This isn't a bug.

List of things that prevent all kind of progress:
- Seeds (except a few special ones)
- Challenges (except for their reward obviously).
- Daily Runs.
- Reruns and Victory Laps (except for a few specific unlocks).
- Any active mod from the mod menu before Mom is killed once on that save (no matter what they do, other saves are irrelevant).
- Enabling the console before Mom is killed once on that save (even if you don't use it).
- Paranoid antivirus programs (or missing rights) preventing the game from creating/editing its save file.
