PacketEvents 2.0 failed to inject randomly

[SergioK29]

Describe the bug
Randomly players while joining will get kicked with "PacketEvents 2.0 failed to inject"

Software brand
Paper 1.20.4, paper 1.21 (this issue has been around a long time, since 2024-02-10 until present day)

Plugins
Protocollib, vulcan, grim

How To Reproduce
Randomly players will get disconnected when joining, its quite rare so hard to replicate, it has happened 191 times on my server out of ~150,000 player joins, here is a dump of all https://pastebin.com/GqBE0v0z

I assume this is because there is some kind of conflict/data race between protocollib, the shaded packet events in grim and the old shaded packet events in vulcan?

Expected behavior
Shouldn't kick them

Additional context
What causes this error? Is there some way to make packet events more fault tolerant rather than just kicking?, maybe some debug flag to println that I could enable and if it happens report back the debug data?

Your having the same issue, eh? It's not rare for me though. It happens every time anyone tries to join.

I am also getting this error every single time on 2.6.0 with Purpur 1.21.1.

Actually updating Better Chat Bubbles to the latest version fixed this for me just now.
