You have always had to read or listen to several sources.
Some sources are less biased than others. E>g. in the UK the print media is biased and readers do know which way e.g. Daily Telegraph is right wing and Guardian is left wing. The broadcast media is less biased as there is legislation to form some form of control. Most of the broadcast media get complaints from both left and right wing - although GB News seems to be firmly right wing.
Bias will always exist, so identifying it and consuming the spectrum is the way to see it. Seeing bias is better than avoiding it, as it helps you understand others perspectives (as they consume biased news.)
allsides.com is good. Modo News is good.
These are the people whose job it is to make complex topics understandable for both parties of congress. Its a fantastic source if you want to set aside 10 minutes to quickly digest a complicated topic (that someone from congress wanted a report written about).
For a fun example, see some of their reports on Directed Energy Weapons: https://crsreports.congress.gov/product/details?prodcode=R46...
Its not really a news source, but then again you did not actually specify news and I wanted to shill CRS since they do fantastic work given the tightrope they probably have to walk every day.
There's the bias problem, and it's one you can do something about!
The best you can hope to do is listen to a range of smart people who are transparent about their priors.
It seems that everything from mass media to small tiktokers are so biased, I can't believe anything they say.
