Problem with Java...

[marcob9999]

Hello everyone.
I have installed REW (REW_linux_5_20_RC12.sh) on Linux 21.04 (Hirsute Hippo) , and I have a problem when I try to create a waterfall.
It gives me this error:

REW V5.20 running JRE 1.8.0_292 64-bit on linux 5.11.0-25-generic, it, IT, UTF-8 at 96 DPI

I've already tried re-installing java8 (sudo apt-get install openjdk-8-jre), and re-installing REW, but nothing changes ...
Can someone help me?
Thanks so much!!!

Best Regards.
