Tabby plugin in Rider gets unresponsive

Autocompletion gets unresponsive quite often. If I reopen the file, it starts working again.
I always use an auto-completion setup.
It doesn't happen immediately. Autocompletion works very well for a while, but suddenly it stops working; I cannot notice any dependencies. However, I've noticed that once I reopen the same file, it starts working well again.
