4.5 does not work

Chromebook/Linux i5 8gig

Just upgraded to 4.5. Program will load from terminal same as 4.4, 4.3, etc. Then Nothing. Totally locked....crashes. Nothing works. Cannot even just shut down program. Have to wait for 'force close' window to pop up!

Same things happen if I try to run from apps files button.

I have to run from terminal with 'qt' app Marc shared with me back at 4.x. Allows me to actually read the menus.

So what gives? I can do nothing now with 4.5. Some Help, please!
