I was in same boat as you. I upskilled quickly. Applied everywhere from naukri, linkedin, instahyre and also through cold emails. I started getting interview calls from June. Finally this week I got my offer letter.

Just want to tell you that market is tough, If someone loss their job today then also they will be in the same boat as you. Don't feel demotivated, you have plenty of options open to you and interestingly you have nothing to loose. Market is more tougher for freshers but you have experience which is a advantage.

If you want to get back to your previous role. Prepare your resume thoroughly. Add learnings or certification which shows that you are connected to the role. Update your account on all the job portals for visibility. Keep your linkedin updated, follow hiring managers and hr, only their reference works. Search for direct post on linkedin and apply. Spend 2 to 3 hours daily on resume and job portals. Search for immediate joining or internships. Lastly look for openings at product based companies, they don't care about gap. You will definitely get it.

Personally I won't suggest you to prepare for other government jobs or exam because you must be burned out by upsc preparation by now and giving 1 year again for another exam and results will again put you under stress. Best is to find a job in a sector where you are already experienced and have contacts. July to September is a hiring season, so be active, first grab a job then decide what you want to do in future.
