Could you please provide some more information?
Which web server are you using, which kind of request you are trying to profile?

I'm using nginx version: nginx/1.10.3 (Ubuntu).
Actually, it happens on every page.
I tried to debug it. in $this->data I receive the string instead of array:

/usr/share/nginx/html/dr8_dev/modules/contrib/devel/webprofiler/src/DataCollector/RequestDataCollector.php:74:string '[
  method => GET, 
  format => html, 
  content => , 
  content_type => text/html; charset=UTF-8, 
  status_text => OK, 
  status_code => 200, 
  request_query => [], 
  request_request => [], 
  request_headers => [
...

I will continue to debug and will provide more information at what moment it is converted to string.

So, after an active debugging process I finally was able to find it.
The value is stored in database and it is stored as a serialized string and it comes there as an string already

{s:4494:"[
  method => GET, 
  format => html, 
  content => , 
  content_type => text/html; charset=UTF-8, 
  status_text => Not Found, 
  status_code => 404, 
  request_query => [
    q => /modules/contrib/devel/webprofiler/css/app/dashboard.css.map
  ],

So, I started to check it and found Symfony\Component\HttpKernel\DataCollector\lateCollect()
which converts $this->data to cloneVar and as the result it returns a string.

I have checked 8.3. There the version "symfony/http-kernel": "^2.2|3.*" is used and this code does not exist there.
Where as in 8.4 the version is "symfony/http-kernel": "~2.7|~3.0".

which converts $this->data to cloneVar and as the result it returns a string.

Yes this is the problem, but I don't understand why the unserialize doesn't recreate the array back. A quick fix is to override the lateCollect() method to avoid the data conversion.

after applying this patch i get :
