Can confirm in 25w02a
I don't think this is a duplicate of MC-151793. I just checked some ominous banners in my survival world, all obtained in 23w12a from both patrols and raids, none of them have the RepairCost that is causing my bug. It seems that MC-166329 was incorrectly marked as a duplicate because the issues look very similar but are actually caused by different NBT tags not working as intended. In this case a tag that only shows up when manually renaming something.
Update: My launcher just got an update and I can no longer reproduce the bug so It's probably been fixed already
Affects 1.17.1-pre2
Can confirm this bug also occurs with dark oak signs (in multiplayer, but assuming it's no different for single player). The crash only occurs when the sign is actually visible on the map, when the sign is covered with a block everything seems to be fine.
