the maximum number of addresses you can technically create from a seed phrase is so gigantic that you will never reach an end because it is as big as the number of private keys. the problem is that you are generating a lot of them on the fly inside your browser which is storing them in your memory with a lot of overhead of additional public keys, addresses and all the calculations that go in them which is why you face an error.
there is no logical reason why someone would create that many addresses in one place inside one loop anyways.

I saw your post on our local board and it seems you're somehow afraid that the address you generated can be accessed by other person accidentally. So, my guess is, you want to create as many address as possible to spread or to be used for securing your money.

While the reason is good, I think you don't have to have 1 million address in order to protect your Bitcoin. The chance of the other person generate the same key as yours is very small. If you're that scared you can change your address once in a while, but no need to generate 1 million address and save it for later.

It is definitely rare that somebody would generate the same address as him. One thing he should have thought is how would the other people would have generated the addresses if he would use most of them.
OP,  generating so many addresses is not a solution to securing your funds if that's what your motive is. You could simple store your funds in an offline wallet if your motive is just to keep your funds secure.

Since his concern is another people accidentally generate address he used, then store his wallet files offline can't help at all.

What he should do is using wallet which uses random that secure enough for cryptography, even though Electrum already uses PBKDF2.

i got error when generate 1 Million btc address on iancoleman, how much maximum address when generate 24 phrase seed BIP44?

Bitcoin's current private key space is 2^256 (ie. 10^76) with Bitcoin's legacy address space being 2^160 (ie. 10^47) due to its use of RipeMD160. (I have no idea about Bech32's address space though)

That's the theoretical limit of how many addresses you could generate with a HD seed. Literally millions of millions of millions of millions of millions of millions of addresses. To be fair it might well be that every seed is capable of generating only a subset of available private keys but even then you'll run into physical hardware limits before you reach mathematical limits.

Bitcoin's current private key space is 2^256
Keys are chosen based on the order of the generator of the specified elliptic curve. Bitcoin uses a curve that has a G with an order that is slightly smaller than 2256 so the space is technically smaller than 2256.

with Bitcoin's legacy address space being 2^160 (ie. 10^47) due to its use of RipeMD160. (I have no idea about Bech32's address space though)
Bech32 (like Base58) is just a method of encoding the same exact data that is the result of RIPEMD160 so it is limited by the same size (20 bytes hence the 2160). In other words in legacy addresses and native SegWit (Bech32) addresses you are encoding the same thing. You can take a look at this topic that I posted a while ago if you are interested to know how it works with an example. The steps 1, 2 and 3 are the same with Base58, Bech32 or any other future encoding we might use.

i got error when generate 1 Million btc address
it should be make your pc stuck and error, you have to try 100k first step by step to 1 Million address. i have already did 100K address generated and eat my 4 hours time. you have rest time to do that, about 24 - 48 hours and better if you already VPS to do that
