Code analysis:

In 24w14a Filterables Codec was changed from using the field name text to using raw. To adjust for this ItemStackComponentizationFix was adjusted as well. However ItemStackComponentizationFix is only run when upgrading format from 24w08a to 24w09a, so this fix won't be applied to any worlds created between 24w09a and 24w13a. To fix this a separate datafixer needs to be added instead. The fix in ItemStackComponentizationFix should probably also be reverted as it may have the same effect as this bug on worlds from pre 24w09a upgraded to 24w09a through 24w13a (untested)

I have created a simple fabric mod to fix this issue: MC-270325

Simple code analysis (official mappings):
PlayerScores

public boolean remove(Objective objective) {
    return this.scores.get(objective) != null;
{{}}}
This method is used by the Scoreboard to remove a specific objective from a "Player", but the current implementation doesn't remove it.
To actually remove the objective entry from the scores Map, it needs to be replaced with something like this:

public boolean remove(Objective objective) {
    return this.scores.remove(objective) != null;
{{}}}
I have written a simple fabric mod to fix this bug!

Confirmed for 19w02a

We have our world since 18w43a, but I do not think, that that is the error
