Cannot reproduce in 19w38b, 1.15.2 or 20w08a; pillagers holding the wrong weapon or no weapon stand with their arms at their sides (similar to non-aggressive skeletons) and don't attack. If anyone else is still able to reproduce this, please comment here.
Edit: MC-160787 seems to suggest that this affects Multiplayer only.
I can reproduce this, but this happens now only for Vindicators. This can be confirmed for 1.15.2 and 20w13b. Can I request ownership, so I can chnage the name and update this ticket?
@Vladimír Is the issue with vindicators holding up their arms (or their attacking animation) happens in singleplayer or multiplayer?
In singleplayer
It has fixed in java 20w29a snapshot,does it will fix in bedrock too.

BOBOIBOY the bugs on the java tracker mean they only get fixed in java not bedrock. If it is an issue on bedrock then submit a report to the bedrock tracker. Make sure to search first though incase someone has already reported it.

How is it possible? I remember that Pillagers without Crossbows cannot attack, not even put their hands up!
@BOBOIBOY SUPRA this bug is not in bedrock edition.In bedrock they can't hold they're arm up in air because pillager can't break their crossbow in bedrock. Ignore the celebration.
ZYX_2D most likely has to do with the fact that pillagers raise their arm like this when they attack with an axe. Reused melee attack animation?
Is this still an issue in latest snapshot and do you have reproduction steps?
