Hello I have been trying to use the new version of processing but to no avail.  
The program does not boot at all after double clicking it. It does not apear in taskmanager  
yes it is unzipped.

I tried uninstalling it and reinstalling it.

I tried running it as administrator,

I tried troubleshoot compatability

I am trying to use it for school and a few other students also apear to have to same issue.

Some other (maybe) noteworthy things might be:  
-PC build  
-beta 6 version  
-using onedrive on this computer  
-processing 3.5.4 does work.

Thank you for your help in advance!

> And again with the latest Processing 4.0 beta 1 (August 9, 2021) It was fine for a few days… I am getting this as of this morning: It may be a false positive as it was before.

I had this recently with Processing 4.0b6 with Windows Defender on W10:

I did a “Restore” of the file after I tested it here:
