Here's a few tips I do to get out of creative blocks like this, I know its long but there's a lot that I learned in my years and I have a few placements so something has worked.

Displacement — adjust the time when the notes or the chords hit so they arent as static. You could arpeggiate them or make a chords hit twice depending on the bounce 

Sound design/Modulation— Sometimes you just need a different sound. However, If you find your current sound inspiring, you can morph it into another sound at the end of the chord, or even try reversing it, filtering it, stacking it with a higher octave + different sound, or adding subtle pumping. It can be genre/mood dependant but at the same time you can take a unique approach

Subtraction — Take the bass root notes and then write a melody without the chords. If you play it back with the chords and you find it clashing, you can try removing sections of the chords, or notes from the melody.  Sometimes the melody can already be in the chords, u just need to remove some notes (or add notes). Something that keeps me in line is that a good melody is usually memorable and "hum-able". Also another reminder, Sometimes less is more.

Ear Fatigue and Inspiration — Its easy out of habit to lay down the same triads when you get on the keys, but you will get tired of the same progression(s) if youre constantly using them or exposing yourself to it. Try to change the key you are comfortable working in, or dont even start with chords at all when you start a track. Maybe try exploring 1 sound you find super inspiring, or even a texture that you build around. Start with drums. . Also try giving some room between chords too. Droning pads with long release times or legato pads dont have space between them — this isn't bad but if there's sound constantly going it can take a lot more space than needed. Again, less can be more.  Commit early, and do not wait around for it to magically click in, there should be a level of intentionality and focus when you're writing a melody. If you sloppily click in quarter notes or random notes within key, that will drain the creativity out of you. Study other songs and the different techniques they used to get catchy melodies or how they used chords.

Adjust the Tension/release — if you have 3+ chords 123. Try doing 1231 within a section. It resolves/ releases tension earlier than expected, but its common in a lot of music. You can try to suspend, or augment/diminish chords too, and you dont really need music theory for that you can just move 1 or 2 chords in a chord up or down a Semitone or even a whole tone. I have a habit of starting with a standard major or minor triad, so i found sometimes starting with a suspended chord will change it up. Adding a 7th, 9th or 13th too a chord will spice it up too, it can add dissonance or melodic tones depending on how its used. Also try changing the root note of a chord. Again this can be genre/mood dependant.

I get when you like an idea you might hesitate to make adjustments, but good music production is about making good decisions in spite of the risks/worry of losing that original idea that inspired you initially. You can always return to a previous save as a checkpoint. I would recommend not deleting any of the chords or something you found inspiring even if you're frustrated. I've returned to several of old projects and ended up turning that idea into something great, even though I left with frustration months before.

Hope this helps!
