Trying to remove call participant using method described here https://learn.microsoft.com/en-us/graph/api/participant-delete?view=graph-rest-1.0&tabs=java
It's been working fine for CVI licensed accounts, but produces the following error for a Development account
error -> {JsonObject@7934} "{"code":"9999","message":"Unknown internal server error.","innerError":{"date":"2021-07-01T14:26:18","request-id":"de149e4c-e316-4682-a539-0ccdac07c86f","client-request-id":"a15f1853-9973-420b-9c5c-1c6cc1080451"}}"
Wonder if I'm doing anything wrong here. "AllowRemoveParticipantAppIds" permission is granted.
Thanks!

According to your description, your issue is more related to Teams API, which we do not support . So I will add teams-app-dev to your thread. Thanks for your understanding!
According to your description, it looks like this issue is related to your account. Could you try to remove participant manually in Teams client to see if it works for you?
