Around 2 weeks ago my ccleaner icon become blank, I tried to reinstall it 2 times but still the same.
It can happen now and again that Windows loses track of desktop icons.
Have you tried resetting/rebuilding the Windows icon cache?
See here for how to do that:

Sometimes with Win10 restarting the computer will cause it to refresh the icons.
perhaps set a the cclenaer icon new?
rightclick on your ccleaner empty icon -> contextmenu -> properties -> (objective/target: make sure that the path of the ccleaner installation is specified there --- for example -> C:\xxx\Piriform\CCleaner\CCleaner64.exe)
-> other symbol -> choose the known ccleaner icon -> ok
