Bug when resize partition

i have unallocated in partition but i can’t use it or take it out this partition(you can understand my partition is 36Gb and then i resize it is 70Gb but i just can use 36Gb and 34Gb is still unallocated ), so everyone can halp me?

You need to resize the filesystem in that partition as well.
Your partitioning tool probably has such an option available.

i resested my computer but in that time i can’t resize or do anything to that partition
