Mozilla Firefox Quantum ESR_x64

Just built the new winpe with Mozilla Firefox Quantum ESR_x64, but getting a error on Mozilla Firefox Quantum ESR_x64 on startup.
Enclose screen shot and log file. 

Hi

re: Mozilla Firefox Quantum ESR x64
I must admit, whilst it's not a problem for me, (I only need one browser) it doesn't work for me, all seems to build fine - no errors, just on launch I get just loads of icons flashing all over the screen (presumably a graphics prob) but no Firefox QuantumESR window, whilst IE, Chrome and Firefox ESR 52.9 will all run correctly. Not just from latest build -  been happening for a while

Edit:
On further testing, can verify MFQ ESR  working fine on a booted usb drive, only giving that error in a  VirtualBox VM
