Fatal Error: Unhandled exception when starting quartus GUI in linux (21.1)

Hi annekri,

Sorry to hear the bad experience you are currently facing. Before we proceed further debugging, can I request the information of the Ubuntu version of your Linux machine, is it version 22.04 ?

Unfortunately and to be frank, Quartus Prime Standard 21.1 Edition is not supported on Ubuntu with 22.04 version. (Picture and website link as below for your reference)

Therefore, here's another workaround for you. You may want to download Quartus Prime Standard with 22.1 version or higher in order for you to run smoothly.

I think this might be able to solve your problem. Please do not hesitate to ask me if you have further inquiries. Do also let me know if this solution works for you

Best Regards

Hubert
