There are a number of workarounds you could attempt and things to check:

1. Position: you want to play in the best possible position for comfort and ease to place your fingers properly. This is something you can play around with, raising the neck up, adjusting the shoulder and elbow. Certain chords may require you to come at the fretboard differently.
2. Pressure: when we’re learning we have a tendency to press very hard, trying to eliminate the buzzing or thuds. Getting the finger closer to the fret wire means less pressure will still work. We need to find that sweet spot where it’s a clean note but minimum pressure. This is still something I focus on everyday, because I still press to hard when making certain chords, like the D major.
3. Light strings: make it easier by using lighter strings. This will change the tone, but there are lots of options and you might find you like the brighter sound. Also, every guitar has it’s “soul mate” when it comes to the marriage between the guitar+player and strings. I recently switched my favorite guitar to D’Addario EJ11-3D Light Guage and I was absolutely floored how beautiful my guitar started sounding to my ears.
4. Tuning: @jorgemac should advise you here, but you can tune your guitar down a 1/2 step or even more, makes it much easier to fret. Great for practicing and I believe he said he slaps on a capo to play along with the challenges. I haven’t done this myself but I’m going to eventually.
5. Nails: always have the finger nails on your fretting hand trimmed as short as possible. This is essential for beginner players.
6. Based on your question I assume you are a new player. You may not have developed callouses on your finger tips. As you do, this will help with the issue of string muting.
7. Make sure you are fretting with the tips of your fingers, the strings should be making their indentation marks about 1/10 inch (2mm) from the finger nail. Much further than that and you’re fretting with the pads and that’s going to cause muting.
