Error detected in MG5 run after upgrade to Catalina on macbook air

Dear Olivier,

I have MG5 V_2.6.6 on my Macbook Air. Once I upgrade to Catalina v_10.15.1, I found the following error.

note : I have imported model - SMEFTatNLO_U2_2_U3_3_cG_4F_LO_UFO-LO , where I set NP=2 while generating the event and kept the parameter as default in their param card.

MG5_aMC>launch pp2twz_NP2_SMEFTatNLO_U2_2_U3_3_cG_4F_LO_UFO

The following switches determine which programs are run:
/=====================================================================================\
| 1. Choose the shower/hadronization program shower = OFF |
| 2. Choose the detector simulation program detector = Not Avail. |
| 3. Choose an analysis package (plot/convert) analysis = MadAnalysis5 |
| 4. Decay onshell particles madspin = OFF |
| 5. Add weights to events for new hypp. reweight = OFF |
\=====================================================================================/
Either type the switch number (1 to 5) to change its setting,
Set any switch explicitly (e.g. type 'shower=Pythia8' at the prompt)
Type 'help' for the list of all valid option
Type '0', 'auto', 'done' or just press enter when you are done.[60s to answer]
