CO-Release Build 21364 to Dev Channel + KB5003397 + KB5003402 to .1011

Greetings to my fellow  early bird  birders.

I have a question , since I rejoined the preview program a couple of years ago I've only had 2 times were issues surfaced and were corrected .   this past week  I've noticed  issues with  browsers  and windows itself just freezes and does not respond .  3 days ago after the last update NORDVPN started acting up  and would not connect after chatting with them , they had me run their diagnostics and they found a issue with UDP  usage and their system , I've had the UDP setting on for 3 years without any issues, they had me switch to TCP  and instantly their VPN app was able to connect. 

Without having VPN on, (my mode of use for 99% of the  week,  I have noticed Firefox just stops responding , funny thing is it let's me scroll , but when I click on links nothing , then 30 seconds later it just works.

the keyboard and mouse are almost new (logitech ) using default W10  drivers 

I'm  sharing  this info just to ask if any of you are seeing any thing like this lately from say 04/15/2021 to today 04/27/2021 

@rtoledo2002, 

I have NORDVPN, I just tried using it with Development Build 21364 and I get an error message.

Latest NORDVPN update got up to 6.35.9.0. also noticed that during the update it installed Visual C ++.

The Login procedure for NORDVPN seems to be changed, I also have problems connecting,  it pops up a notification message Stating "NordVPN failed to turn on NordLynx"

So I switched the VPN Protocol to "OpenVPN (TCP) and it finally connected.

It was set for "Choose a VPN Protocol and Server automatically"  and that gave me the error above.

I just saw that there is a newer version of NORDVPN 6.36.6.0, I have that on 20H2 system, but have not tried on Development build 21364.1000 yet.

The strange thing is that on the NordVPN site the latest they show for windows is 6.35.9.0, but my laptop was just updated automatically to 6.36.6.0, perhaps it is still a Beta version ? 

Edit:

Tried NordVPN 6.36.6.0 on Build 21364.1000, I see no difference from previous version, still had to select OpenVPN (TCP) to get it working.

As for Firefox I don't see any unusual delay with or without NordVPN..

Some users that have WSL enabled are reporting delays of file explorer and other functions, it is also mentioned in the 21364 blog and 21359, do you have WSL installed ?         .

I had the same issue as FG last night on my Desktop PC

and resolved it the same way.

This AM when I booted the Laptop and it checked for

the Def update it also got the error, yet the Def # was .41.

Manually went and got it, then W.U. was fine.

From what I have seen on 6 different machines with 20H2, 21H1 or Dev builds, the Error 0x80070643 was occurring the 1st time it tried to update defender from 1.335.xxxx.0 to 1.337.xx.0, once the update to 1.337.xx.0 was successful every update after that worked fine with W.U. 

It has done several defender W.U. updates with no problem after the errors that occurred yesterday which were all resolved yesterday by manually checking for updates directly from defender. 

I haven't seen anymore errors today on any of the machines that failed previously. 

I've seen the same error with previous development builds not long ago and was also reported by other users with build 21359, the workaround was the same, just by checking for updates directly from defender.

Hi Johnny, 

I'm sure the problem was on their end.

Try the update from defender directly, it worked fine for me and then the next update worked normally with W.U.

Same on all 20H2 machines.

Just tried today, same device, WU installed it.
