MySQL wont run on Ubuntu 20.04.3 LTS

I've been going round and round trying to solve the below issue when trying to start MySQL:

2022-01-27T09:47:14.547946Z 0 [Warning] [MY-010139] [Server] Changed limits: max_open_files: 1024 (requested 8161)2022-01-27T09:56:22.047681Z 0 [Warning] [MY-010142] [Server] Changed limits: table_open_cache: 431 (requested 4000) ...2022-01-27T09:56:22.265005Z 0 [Warning] [MY-010091] [Server] Can't create test file /var/lib/mysql/mysqld_tmp_file_case_insensitive_test.lower-test

I've tried upping my limits.conf file values, and in /etc/service however those values are all over 10000 (or in some cases 65535) however no matter what I change when I run:

ulimit -Sa | grep "open files"

The result is always:

open files (-n) 1024

Any help would be appreciated but I just can't see any other solutions?

I have no databases yet, I've not even managed to boot MySQL to log in once.

MySQL is Ver 8.0.27Running on Ubuntu 20.04.3 LTS on WSL
