Up Studio v2.6.49.627 hangs on start

Was all working fine until I rebooted my laptop this morning.
Now Up Studio just hangs at the splash picture.
I’ve tried running repair, uninstall/reinstall, cleared cache in appdata\local\TierTime

but its still tear time .

When I try to install the 32bit version it fails with the message: “ended prematurely because of an error” which gives exactly zero information; ending prematurely is an error, what about a reason or error code.

I’m on windows 10 64bit

Any suggestions how to get it going again ?

I’m thinking of buying another printer, sick of being tied to unreliable software.
