Error decoding JSON data: Control character error, possibly incorrectly encoded

Hi Jose! Hope you and your family are fine and healtly
See i have this site with SCP and recently i have to use JCH Optimize to speed up the site and get bettter rank at Google Speed Insights, the jchoptimize generates multiple files in a php files wich are stored at cache folder. When i check my SCP i see all these cache files listed as possible malware, y sent those files to Metadefender cloud and i get 0 positives of malware, check my self the files with CP Filemanager and everything looks normal, so i select the listed files and add files as save, then i get the error at font and backend  "0 Error decoding JSON data: Control character error, possibly incorrectly encoded", all my teamworkers began to scream because they cant access to the site and clients cant visit our catalog... so after many tries to disable plugins "extensions" from phpmyadmin i see that the error was with SCP. I have to disable in order to everyone can work, but i do not like at all to have my site without the strenght of SCP. If i try to enable back i get the error again, i was searching maybe emty cache or something, Can you please point me in the direction to solve this?
Thanks in advance for your support 

P.D.

Hi again Jose
I found that the problen is with the format of "params" field of Securitycheck Pro on xxx_extensions table, to be more precise at the close of the line, maybe it was unable to store the data in to the field, i have to add the closing characters
"} at the end and now it works fine
Thanks!
