Out of memory error compressing to zip using zstd with level 20+

[pps83]

I use 7-Zip ZS 22.01 - v1.5.5 - Release 3 that seem to be very outdated compared to the src code. I wanted to do some tests with .zip + zstd and simply wanted to compress src code of the latest lzma sdk. If I use .zip+zstd with compression levels above 19 I get "The system cannot allocate the required amount of memory" error:

these are the compression settings:

7z+zstd with 20+ compression level has no issues, so it's some sort of bug in the code. Total uncompressed size of the code is less than 10MB.

Can confirm it with current master too, however only with level 22 (seems to be depending on max memory).

Attempts to reduce Memory usage for Compressing (no matter to which value), in order to workaround it, cause another error - "The parameter is incorrect".

I have also noticed this issue. On my computer, no matter how 7z is set up, this error occurs, while other formats do not have this problem
