After upgrading to NVDA 2019.2 NVDA became totally not functioning

Mr. Wong Chi Wai, William <>

After upgrading to .2 this morning, my NVDA became totally not functioning.
I have 2 issues:
1 Since NVDA is not making any sound, I cannot create a bug file.

2 I need a NVDA 2019.1.1 installer yet I cannot find that from the releases page of the NVDA.
Could anyone provide me a official link to the download?
