game freeze, reload after a minute or close without warning

my game has been freezing and sometimes crashing to desktop all league. Sometimes it will freeze for a minute or two and then go black with grinding gears while it reloads the map and resets the minimap, but recently it's just been freezing up and then crashing to desktop. It seems this is always accompanied by a warning in the logs as the last known thing, this being the most recent one:

2025/07/18 12:12:24 41507734 3796f60d [WARN Client 23188] Matching object found for InstanceClientActionUpdate, but no matching action was found on object to update.
Action Id = 52933
Detach Id = 0
Skill Type Id = 46185
Skill Instance Id =32768

Whatever "skill instance ID" is, it seems to usually be the same few numbers. for example, that one shows up a lot, and so does 32772. Are these microtransactions, and if so, which ones so I can disable them?
