This should NOT be hard to figure out. It isn't even allowing "counters!"

When I use Domris ability to get Mana and try to cast a spell, the mana floating by the Planeswalker is always used although I like to keep it in my pool. I can't use Mana from my lands to cast a 2 cmc spell, it always uses the one Mana floating, which is important, it grants Riot or makes the creature uncounterable, but it is always used and I can just pay 1 no matter how I tap my lands or even when I use full control.

What do I do? Me and opp are froze into the match. No options available.

My opponent was playing a 5 color combo deck in historic. The deck had tamiyo, black leyline, eerie ultimatum, fall of the thran, and omniscience. The game reached a point where the opponent had no more cards in deck. Two turns passed while the opponent had no cards in library. The opponent had a stop on upkeep, and somehow went two turns without having to draw from his deck. I am not sure if he was exploiting a bug, or if I missed a card interaction. Please find my log attached.

I am having trouble downloading the current update, when I download it gets to somewhere in the 100-200 mb range and then just quits. No warnings, no errors. I restart the arena client and the download restarts from scratch (0mb).

First bug is the crash, there is also a design flaw in forcing as many updates as the arena client does and no ability to download the update in parts or resume. Made worse now by this odd bug.

I had both a psychic corrosion and a Teferi's tutelage in play. I believe I cast the corrosion first. Afterwards, tutelage never triggered on a draw. I even cast another corrosion and it was if the tutelage wasn't seeing the draw triggers because they were in different layers or something.

Arena crashed in the middle of the game and I lost a ranked match

In my deck from the jumpstart event, the number which shows the ammount of copies included in the deck is missing at the swamp.
Like there's only 1 swamp in the deck.
In Deck Details the number of swamps is 7, which is correct.

I didn't receive the wildcards after the ban in Histórico!

The special card design for Garruk and i guess for the other cards as well has the error, that it does not show how many copies you play. I play three but it does not show x3

Completed a Jumpstart game. I inspected the reward card I got and encountered unusual UI overlapping coming from the gold and XP rewards partially showing through

First game each session results in a freeze immediately after matchmaking. This usually lasts just long enough to forfeit the match. Does not occur in subsequent matches even if the client is closed and restarted. Happens consistently based on below steps, see attached log.

Steps to Reproduce:
1 Restart Computer
2 Open MTG Arena Client
3 Start any type of match
4 Issue occurs

On start up, I get a warning pop up from Arena telling me there is an 'Invalid Command Line'

Arena is UNINSTALLED on my PC. Why am I even getting a notification from it?

When playing in the historic traditional ladder I am unable to sideboard, when the first game is done I switch cards between sideboard and main board I press done and then it goes to loading screen for the whole 140seconds and then the new game starts without any of the changes happening. It was happening before in the traditional historic event but now it is happening in the ladder.

When trying to cast Heliod's Intervention to destroy enchantments, Arena made me pay XX instead of just X.

When playng Assalt Formation and Wall of Blossom on Jump Start Event, my opponent, was able to atack with the Wall without paying the cost of the first abilitie of the Enchant.
