await member.remove_roles(member, role) - discord.py

Question

I'm using discord.py rewrite. I've been 3 days trying to get these two lines of code to work:
await member.remove_roles(tryMember, tryRole)
.
.
.
await member.add_roles(tryMember, tryRole)
here is the surrounding code including my troubleshoting comented out. I have user ID# and role ID# to work with. This is a background process.
memberList = []
for member in guild.members:
...
... decide on one of 3 roles for the user as proposedRole. # role ID number
...
for roleID in (serverSettings["inactive_r"], serverSettings["active_r"], serverSettings["very_active_r"]):
if roleID != proposedRole:
try:
print (roleID)
tryRole = discord.utils.find(lambda r: r.id == roleID, guild.roles)
tryMember = discord.utils.find(lambda m: m.id == member.id, guild.members)
print (tryRole) #only prints a member's name#number
print (tryMember) #only prints the role name
await member.remove_roles(tryMember, tryRole)
print (f'Removed {tryRole} from {tryMember} in {guild.name}')
except Exception as e:
print ('There was an error running this command: ' + str(e))
... And repeat all this but adding the right role instead of removing the inocrrect roles
What gets printed out on the cosole per member is this:
709425978044186725 # the correct role ID
inactive # the correct role name (I was expecting an object)
ArdenFutura#2469 # the correct member name (I was expecting an object)
There was an error running this command: 404 Not Found (error code: 10011): Unknown Role
# the e exception
664856898838855681 #aaaaand repeat...
active
ArdenFutura#2469
There was an error running this command: 404 Not Found (error code: 10011): Unknown Role
726974763649728593
very active
ArdenFutura#2469
There was an error running this command: 404 Not Found (error code: 10011): Unknown Role
Ive been 3 days on these two lines of code. please help.

You may be confused with an older version of the API Reference. remove_roles used to take two parameters:
remove_roles(member, *roles)
However, the new documentation states that only one parameter is required:
remove_roles(*roles, reason=None, atomic=True)
roles takes in a single role. If you wanted to remove multiple roles, a list of roles with an asterisk preceding the list would be passed in (remove_roles(*[roleOne, roleTwo])).
reason and atomic are optional parameters of type str and bool.
In your case, you are trying to remove tryRole from tryMember. The result would be:
await tryMember.remove_roles(tryRole)
