The rim profile height isn't a reliable estimator of ERD. Because different rims have different depths of the tire bead seat location in relation to the top of the rim wall.
So for example, if the new rim has the exact same profile height, but the bead seat deeper down the wall, then the ERD of the new rim will be larger because the spoke holes are higher up and closer to the bead.
As the other people have already mentioned, the only way to find out the real ERD of your rim is to either measure your spoke lengths and calculate the estimated ERD from the hub dimensions, or measure the rim itself.
Here is a French seller of Sun Ringle rims but they're only 20". You might ask if they can source a larger diameter:

ERD chart. It's old, so I think you have to click the individual rim page to find out if they come in 622.

I've never used Sun Ringle.
Halo sells rebranded rims. Some of them are Kinlin, but you'll have to ask them for confirmation. The one called White Line classic is about the same profile dimension as yours. Shipping from UK is reasonable. I've never used Halo rims.

There is a German seller of Kinlin rims, the German and English version sometimes have different descriptions:
