No, the major problem is webMAN still causing black screen when launching other homebrews when webMAN is activated.
Using multiple file manager and updating HEN from previous versions doesn't matter, I already have two file managers and updated 2.2.1 to 2.2.2 through the HFW Menu without errors.
The biggest problem in the HEN is the incompatibility with webMAN while using other homebrews when webMAN is running, it doesn't happens in CFW, there is problem from HEN.
For a time, I tried used HEN without webMAN installed, it worked 100% all other homebrews even multiMAN I used also apps including PSN Patch, Managunz, Irishman all worked perfectly without webMAN, so webMAN is main causing of these issues
