Blender crashes when enabling ClockWorx Music AddOn

Here is what I get when trying to enable ClockWorx AddOn in latest Blender (2.90.1):

found bundled python: /home/myuser/Scaricati/blender-2.90.1-linux64/2.90/python
LLVM triggered Diagnostic Handler: Illegal instruction detected: VOP* instruction violates constant bus restriction
renamable $vgpr4 = V_CNDMASK_B32_e32 32768, killed $vgpr5, implicit killed $vcc, implicit $exec
LLVM failed to compile shader
radeonsi: can't compile a main shader part

renamable $vgpr2 = V_CNDMASK_B32_e32 32768, killed $vgpr2, implicit killed $vcc, implicit $exec

radeonsi: can't compile a main shader part

Then, Blender crashes on activation of the AddOn with: Canceled  (core dump created)

What can I do?
