Can't install or update CB packages

Hi guys I have been getting errors when I try and update or install CB packages both manually and using install from web. I get the following error and aside from the core CB all other installs fail.

"System Information
Joomla: 3.10.2
Community Builder: 2.6.2
PHP: 7.4.23
Database: mysql 5.7.35

Package
File: 067_cbplug_lang_cbsubs_english_en-GB_4.5.2+build.2021.08.07.zip
Log: "

If you're seeing that error then it typically means something has broken the JSON response for the package installer. Usually caused by some 3rd party extension echoing something even during &format=raw URLs. It's possible the plugin installed despite seeing that error. Navigate to CB > Plugin Management and see if that plugin updated fine despite the error.

It seems they aren't installing is there a way I can hunt down the offending extension and uninstall it?

Press F12 to open your browsers developer console then attempt to install something and check the Network tab for the HTTP request to install something. From there you can review its response and see what is happening to the JSON data. An example of a working response is as follows.

URL: /index.php?option=com_comprofiler&view=editPlugin&action=installpkg&cid=56&fld=plugins&pkg=013_cbautoactionsbot_8.1.0%2Bbuild.2021.09.17.15.43.10.d1f5f09a0.zip&format=raw
Response:
Notice the response is valid JSON. If there's something before { or after } then something on your site is echoing data and breaking the response.

They should still be installing though since this is the final step of the process and is just the response message. Try downloading something that's failing manually from our downloads page below.

Next unzip it and find whatever you're trying to install in /extensions folder and its various subfolders then try installing that manually to see if any errors output. Something is directly failing on your site is why the installer is failing. This usually means some sort of top level error is breaking things.

The usual culprit is a 3rd party system plugin loading on every page and causing issues.

Ok firstly I don't understand the results I am getting: 1. I checked the console output and it seems like after trying to install CB Subs something is creating a 403 error that then is included on every request and response. 2. I tried taking just one plugin CB AutoActions and unzipping it on my temp folder in the server directory but when I do that and specify the temp directory the package installer attempts to install all the packages I have in exactly the same manner it did in install from web. I cleared cache and tried again a few times same result. I then manually deleted everything in the temp directory and got the same result. I am not sure a why the installer is trying to update other packages and b what to try next.
