First of all, I want to thank developers for this awesome style. I'm posting this in case anyone runs into similar problem. I got this errors when compiling document:
LaTeX Warning: You have requested, on input line 40, version
`2020/04/06' of package expl3,
but only version
`2021-06-18 L3 programming layer (loader) '
is available.
File ended while scanning use of \__file_parse_version:w.
Missing number, treated as zero.
Additional info about my system:
TexLive (20210706); VScode with extension LaTeX Workshop; Win10

I assume the problem is cause by some version incompability. I found this discussion https://tex.stackexchange.com/questions/581409/expl3-problem-file-ended-while-scanning-use-of-file-parse-versionw which helped me. Basically you can either add \usepackage{expl3} before biblatex (around line 73 in FEIstyle.cls) or you can move biblatex before babel.
