install gparted kernel in omv6 and now dont start nothing [HELP]

hello, I have omv on my proxmox server with a 20gb sda disk and these days I have changed by moving and deleting many files from my storage disks (sdb, sdd, sdc) and I have seen that the root disk space of my omv has decreased (I imagine some kind of cache or something, I don't know)

but in my proxmox I increased the root disk space (sda) by 5gb more but I have not seen that change in my omv5 and now updated to omv6...

I have done an lsblk and it appears that it has 25gb in total but that the sda1 only uses 20gb of which there is only 1.30gb of free space...

so i thought i could install the gparted kernel and from there see the partitions and extend the new space to the omv6 partition, so install the kernel plugin and then install gparted and reboot to get into gparted but now it just shows up

Could someone help me today has been very hard because by mistake I installed omv6 in my production omv instead of doing it in my test omv

EDITED WITH NEW INFO

sorry but all change...

apparently when installing the gparted kernel something went wrong because now when restarting the grub yes window appears

but when omv6 is started, I can enter through the web interface and through ssh, but in the proxmox console, only this black console appears.

and it never gets to show the entire console to enter the credentials, but I repeat yes, it is working, through ssh, through the web interface, I can access all my disks and folders, but in proxmox the console does not work

and if I try to enter gparted this screen appears and it never loads anything
