Interview negative outcome every time!!

I need to pass this interview please help

Guys am 45 years old Arabic guy and was living and working in Dubai for different multinational companies for almost 20 years but 2 years ago I lost my job, however I kept applying and looking for job and got during the last 2 years many interviews but for some reason I wasn't hired till now, many interviews I walk out feeling so confident that I did really well and sometimes I can see the excitement in my interviewr eyes and still don't get picked up.. Now am in a very difficult position and have an interview in 10 days I consider it life or death and I need to pass it by any means so I would appreciate any advise I know am 45 but there is no shame in learning even if from younger people and I need a good answer regarding the 2 years gape that obviously since my previous company closes down past Corona end of 2022 and I wasn't working so how to explain this if I get questioned about it or should I try to cover it up and not bein completely truthful with them and act as if Its just 2 month not 2 years. Knowing that I had claws in my last contract regarding non competition stretching 2 years however it wasn't the main issue . Thanks in advance and please pray for me because I really really need this and it's my final chance..
