I think it is a bug. ModelSim cannot be called from Quartus on Ubuntu

1) I have Quartus Prime Lite 21.1 installed on Ubuntu 20.04 and it is working fine.

2) I also have ModelSim 20.1.1 and it is working fine

3) I've put the right path to ModelSim on Quartus Prime, and it can even recognize the version as we can see on pictures 1 and 2. I've tried 2 variations:

a) /home/domvito55/intelFPGA_lite/20.1/modelsim_ase/bin

and

b) /home/domvito55/intelFPGA_lite/20.1/modelsim_ase/linuxaloem

4) But when I try to run ModelSim from inside Quartus, it does not open! And I get the following message which is pretty odd, as I've never installed Questa, and I didn't even put a directory path for Questa.

Error: You selected ModelSim as Simulation Software in EDA Tool Settings, however NativeLink found Questa Intel FPGA in the path -- correct path or change EDA Tool Settings and try again
Error: NativeLink simulation flow was NOT successful

I've spent all day today trying a bunch of stuff, but I couldn't solve it.

I'll put the transcription of the log file in the end.
