Unable to enter raid/instance/scenario after few minutes online just only playing a character

After the new patch released (legion remix of wednesday) playing my druid is become frustrating.

I cant be summoned or enter instance or raid or m+

The only way I found is to logoff and login again each time (after this I can enter or summoned)

Sometimes also in solo all npc and player disappears and need to logoff and login again.

I disable all addons but nothing change.

If I play another character on the same account with the same addon there is no issue.

I notice that after patch the boduguard npc follow me anywhere( could this the problem?) there is way to dismiss (Is the only thing I have still to try to fix it)

Anyone have the same issue?

try to delete all quests on that character

I finish all the quests of the campain and class hall too

the only quests I still have are the 3 for seals in tomb of sargeras and the meta quests infinite research
