Parallels Windows10 sometimes freezes host system, sometimes won't start on

I want to put this again because this is boring for me all the time about 1 year or more. it happens sometimes not always, happens every 2 weeks or a month once.
yes, It freeze, the windows 10, you say to get the tech report and send it to you, but it freeze I can't do anything even to get the tech report , I have found it is not CPU, It is high disk IO. so all the system, include host MacOS did not respond to any action. slow slow. even to reboot it impossible. no way, then power off mac, after reboot mac then to start parallels it also begins high IO to disk. then freeze. the interesting thing is after several times power-off and reboots it becomes normal. parallels ver 15.1.4 (47270) mac os Catalina, but it also occurs in the previous version of OS and parallels.

 

We suggest you refer this article and check if there is I/O error on your Mac hard disk then let us know the results.

 

I confirmed the system.log, there is no I/O error. If it occurs again I will check this log file again. by the way, my MacBook Pro is new. so it hard to think of sector error of the SSD. And if SSD access error it just gets some file read error, not High rate of IO. and continuously reading and reading... , again I if it happens again I will put the IO rate picture here. If I can capture it. you know when it happens all machine is slow down I can't do anything. Right now Parallels and win10 works normally. ya when it got normal, normal a week or more.

 

And there is no IO error.

Hi, is it possible to collect the tech report data right after the issue reproduced and post the report's ID here?

 

OK, if next time happened I try to get the tech report data.

 

it happened again the tech report data ID is 344411783
it so slow when I get tech report, I am not sure the data is useable.
