I have a M&P22. It ejects fine when fired normally, but if i use my thumb to prevent the slide from moving, then after when i rack the slide, it fails to extract. Is it normal for 22lr to not be able to extract after the fact like this?
Part of the extraction problem is the cartridge starting to move backwards into the slide and the extractor after pressure drops after firing. This pushes the case head out so the extractor can get a good grab on its rim. You are circumventing this process thus causing it to not work as intended.
Trusting your life to the benevolence of an armed criminal is not a strategy, it is stupid!

Thanks for explaining that. Is this true of all 22 LR hosts?

Bolt action rifles don't use a blowback design either. Two completely different designs altogether.
