[UPDATE] The issue ended up being my security software (BitTorrent) being over agressive - I've been unable to make it not stuff up Laragon (excluded laragon folder, and the exe, but it still things files are suspicious!)- so I will un-install it and go back to Windows Defender for now.
This morning I turned on my W10 box, ran Laragon, created a new WordPress site - while it is doing it I switched to another program (I noticed the usual notifications as db was created, etc...) , a few minutes later I went to go back to it, but it was nowhere to be seen - I tried to run it again, and it said the program was no longer available.
I browsed the the laragon folder and the exe was not there!
I restored it from last nights backup, but now when I run it I cannot start anything (see image below)
Anyone have any idea what might have caused this ?
And if I re-install, will my projects remain, or will I loose them ?
