I have observed this happening to me, too. Frogs are not spawning in swamp chunks generated before 1.19 but spawn just fine in chunks generated after 1.19.
I can confirm this. There have been a few changes to the terrain generator since I started my world and there're no frogs in the "old" swamps. The biome is correctly indicated as a swamp but "/locate biome minecraft:swamp" doesn't see the "old" swamps either.
That would be MC-172449.
For me frogs spawned in the old chunks on updating but after despawning, but not a single frog spawned in the old chunks even when it had been loaded in for at least 20 in game days. The locate command does not recognize the old swamp as a swamp even though the water color and grass color are correct
I got the same issue. My world and this swamp was generated in 1.14
Can confirm in 1.19.3 and 23w03a
Can confirm for 1.21.3
Are there any other animals loaded in the surrounding area or spawn chunks?
Or alternatively, could you attach your world where you encounter this issue?
I cant upload the world due to the size limit on this site so i had to upload it to google drive.
and as i commented 2 years ago my swamp was probably made during 1.14.
I did try to update the world to 1.21.3 but the issue remains.
Tried to kill all entitys using /kill @e but the issue remains.
I seem to be able to recreate the issue by creating a new world with the same seed: 6222775103534946325 in 1.14 and then run it in the latest version of minecraft (1.21.3)

@Happy, I was able to observe frogs spawning in the swamp in the world you provided. When you run /kill @e[type=!player], make sure your simulation distance is at least as high as your render distance due to MC-271385. Also note that no mobs will spawn while you're in Spectator mode.
If anyone is still experiencing this issue, please provide a world download.
Issue still remains for me i tried to make a new world again in 1.14 with the same seed and let it load for 5 min and afterwards i ran the same world in the latest version and 32 on both render and simulation let it load for 5 min then i ran the command you sent and were also in creative mode but i saw no progress even after letting the game be in the background for hours.
Ok, I just tested using 32-32 and the command didn't properly clear the mob cap, so I think you're experiencing MC-271385. Try lowering your render distance by at least four chunks after running the command – that worked for me.
