I'm sorry to hear that.
FWIW, I gave up and switched to Bitwarden, where I've not been logged out for weeks. This thread opened 486 days ago. If LP can't fix bugs like these, I'm not sure they're worth my money any longer.
Even if they fixed this issue tomorrow, I've lost a lot of trust and an enormous amount of time.
I hope LastPass can figure it out and get their customers back to not worrying about a little password manager.
