A player drank a witch brew and got disconnected immediately from the dedicated server. When they joined back, every single player in the server got disconnected. I asked for logs, but there is no crash. they sent me a latest.log, which isn't really helpful. Every time the player who drank the witch brew joins, they get disconnected, along with other players.

1.17.1
Fabric 0.20.5
Bewitchment Version: 1.17.13 and 1.17.4

Tested this with just Bewitchment installed and nothing happens. Can you try to find what mod causes this?

Was it tested in single player or a server with people on? If single player, the main issue is using it on someone and they both disconnect themselves and people upon joining, maybe affecting Client Server packets which would not exist in single player.

It was 2 people on a dedicated server

Can you see if this happens using the impersonate command too, or just polymorph potions?

Still seems to work just fine, but if it's still a problem then I would report it to https://github.com/Ladysnake/Impersonate/issues

This happens with any mod that changes the player name. Thinks like luckperms, ftbranks, etc.
