So...
Now it's work fine.
What I did:
I was launched google maps under retro mode. All good. Reload in Ultra mode. All in freezes.Then again reload in retro mode and close tab. Press Button of Open Last closed tab. Opened Google Maps again in retro mode. But page was like as your browser is too old, use new browser. I reload this page in Ultra mode and can see Google maps with fast speed, no freezes.
